A Few Quotations on the Life of Nagarjuna, Lhudrub Nyingpo

 
 
Venerable Thrangu Rinpoche said that it is not really important knowing exactly when a great Mahasiddha or yogi was born, what he ate, how he walked, and the like, rather, “The main thing is that he lived.” A few quotations on the life of one of the most eminent Siddhas the world has known, most excellent Nagarjuna, may be inspiring, although these notes are only fragments that point to an awesome life. Maybe it would be helpful to recollect the early spread of Buddhism according to instructions by His Holiness the Gyalwa Karmapa in order to appreciate the continuation through our luminaries who continue giving us so much: “The phase of early Buddhism: The historic Buddha expounded the teachings and his disciples preserved the teachings. This occurred approximately from the middle of the 6th to the middle of the 5th century B.C.E. The phase of interpretations of the teachings: The beginning of the divisions into various (Hinayana) schools on the basis of different interpretations of the teachings of Buddha (Councils) started to occur, the criterion of the second phase. This took place approximately from the 4th century to the 1st century B.C.E.1 The phase of the rise of Mahayana Buddhism: The rise of Mahayana Buddhism occurred approximately from the 1st to the 7th century C.E. The Mahayana Schools developed especially during the time of Asanga, Vasubhandu, Nagarjuna, and other great masters. The phase of Buddhist Tantra: The revelation of Buddhist Tantras (in Tibet) started to take place after the 7th century. Tantric Buddhism existed in India at the time in an extremely hidden or secret form and was not made public or accessible to the general Buddhist practitioners. It expanded even more during the time of Saraha, Nagarjuna, and other great Mahasiddhas and finally came to Tibet in full through the blessings of Guru Padmasambhava, Marpa the Great Translator, and many other
eminent Indian and Tibetan masters.”2
 
 
Mahasiddha Saraha
 
 
Rangjung Yeshe presented a short biography of Noble Saraha that is readily available and a wonderful support: “Saraha was a Mahasiddha who worked as an arrow-maker and had a consort of the same trade. He composed many songs and dohas describing the enlightened state.”3 Saraha is exemplary because he offered prostration to the true nature of mind, for example in the verse, “Homage to the mind that is like a wish-fulfilling jewel.”4
 
Thrangu Rinpoche tells us on many occasions that the “Mahamudra instructions came from Saraha, Tilopa, and Naropa. They taught through the method of ‘spiritual songs,’ dohas. These spiritual songs do not give a detailed presentation of Buddhism but use practical imagery to introduce the listener to the nature of the mind.”5 Shenphen Osel offered a song of realization by Saraha that underlines the significance of Thrangu Rinpoche’s precious teachings on “The Five Reasonings of Nagarjuna,” instructions that, in turn, illuminate the short verse written by Saraha, which states:
 
Mind is the basis of samsara and nirvana.
Once you realize (its nature), rest in the ease of non-meditation.
Other than within yourself, to look for it elsewhere is completely deluded.
There is nothing of “It is this,” “It is not this.”
Everything abides within the natural state.6
 
And all along Saraha, who was Nagarjuna’s spiritual master and friend, urged his students to unite wisdom with means, because, he said, “Without compassion, the view of emptiness will not lead you through the sublime path.7
 
 
 
Noble Nagarjuna, Ludrub Nyingpo
 
 
Little is known about the life of Nagarjuna. Ken McLeod tells us that Nagarjuna was the “Indian master who lived about the first century of the Common Era. He was one of the greatest dialecticians the world has known, and his works definitively established the ‘Middle Way’ (Madhyamaka in Sanskrit) between the dualistic extremes of origin and cessation, nihilism and eternalism, coming and going, monism and pluralism. As a teacher at the famous monastic university of Nalanda,8 his expositions on emptiness and other topics of Buddhist philosophy are still used today as authoritative guides for intellectual understanding and contemplative practice.
“The name Nagarjuna, kLu-grub in Tibetan, means ‘he with power over the nagas’ – the nagas being a form of serpent. The epithet refers to his recovery of the Buddha’s teachings on the Perfection of Wisdom from the naga-king who guarded them. Nagarjuna’s commentaries on this profound teaching led to the formation of the tradition of Profound Philosophy, which establishes the intellectual understanding of emptiness as a basis for contemplation.”9
 
A few word usages connected to the term naga from the Rangjung Yeshe Tibetan-English Dictionary may help clarify questions that can arise, especially seeing that it is said that nagas protected Lord Buddha from attacks of the maras on the night before his enlightenment:10 klu - Naga. Powerful long-lived serpent-like beings that inhabit bodies of water and often guard great treasures. Nagas belong half to the animal realm and half to the god realm. They generally live in the form of snakes, but many can change into human form; klu khang – naga protector temple, behind Potala in Lhasa, residence of nagas, built by the Sixth Dalai Lama; klu skyes – tree; klu rgyal rigs – nagas as warrior caste (in ornamental symbolism).”11
 
In his commentary to Chandrakirti’s Entrance to the Middle Way, Khenpo Tsultrim Gyamtso Rinpoche taught:
 
The ocean is said to be inhabited by nagas. Nagas are sea serpents and are incredibly clean creatures, which is why, if a corpse ever falls into the ocean, it always washes up on the shore. The nagas will not allow it to stay in the ocean. (…) Similarly, when great beings come under the power of discipline, they do not abide together with the decay of discipline.12
 
 
Nagarjuna’s vast activities
 
 
Legend tells us that Lord Buddha prophesied the coming of Nagarjuna, who lived some time between 150 and 250 C.E. According to accounts, he was born into a Brahmin family in South India and converted to Buddhism.
 
In the Biographical Notes of Rangjung Yeshe it is stated, “An astrologer predicted that in the best case (if he practiced the Dharma), the child would live for no more than seven years. When seven years were almost gone, the parents sent their son away on pilgrimage with a servant, because they could not bear the thought of seeing his corpse. However, Nagarjuna reached Nalanda Monastery and met Saraha, who told him that he could escape death if he were ordained as a monk. Nagarjuna also received the initiation into the mandala of Amitayus13 and by practicing the mantra recitation through the last night of his 7th year, he could free himself from the fear of death. The following year Nagarjuna received the initial monk ordination and became proficient in all the branches of knowledge in both the Hinayana and Mahayana sutras. Saraha also gave him many teachings on the secret Mantrayana. Having mastered all these teachings, Nagarjuna returned to see his parents. Afterwards he took the full monastic vows.
“Once a terrible famine broke out in Magadha and continued for 12 years.14 Saraha asked Nagarjuna to provide for the monks at Nalanda, who were destitute. Nagarjuna decided to learn how to make gold so that he could help them. He took two sandalwood leaves and, with the appropriate mantras, gave them the power to instantly transport a person to wherever he wished to go. Holding one leaf in his hand and concealing the other in the sole of his sandal, he travelled across the ocean to an island where a famous alchemist lived. Nagarjuna requested instructions in the making of gold. Now the alchemist realized that Nagarjuna must have come across the water by a secret technique, so hoping to acquire this secret, he said, ‘Let us exchange either our crafts or our wealth.’ Nagarjuna replied, ‘We should exchange our crafts’ and gave him the leaf he held in his hand. The alchemist thought that Nagarjuna was no longer able to leave the island, so he taught him how to make gold. Then Nagarjuna, by means of the sandalwood leaf he had hidden in his sandal, returned to India. There he turned a lot of iron into gold and provided the whole Sangha with all their needs. Later Nagarjuna became abbot of Nalanda. He repeatedly defeated all his opponents, both the heretics such as Shankara,15 who ridiculed the Madhyamaka view, and the Shravakas, who denied the validity of Mahayana. Some Nagas attended Nagarjuna’s teachings and requested him to visit Naga Land. Having taught the Naga King and his subjects, Nagarjuna returned with the text of the Prajnaparamita in 100,000 Verses and its abbreviated form. With these scriptures he revived the Mahayana tradition. He himself composed many treatises, elucidating the view of Madhyamaka and set a reference point to the whole Mahayana philosophy on relative and ultimate truths.16
“In accordance with the prediction of Arya Tara, Nagarjuna returned to South India to teach. There, too, he composed many treatises. His teachings on Vinaya were equalled to Lord Buddha’s First Turning of the Wheel of Dharma, his teachings on emptiness to the Second Turning, and his Collection of Praises (such as The Praise to the Absolute Expanse, Dharmadhatu) to the Third Turning.”17
 
Noble Nagarjuna was preordained by Buddha Shakyamuni to recover the Prajnaparamita Sutra, which had been entrusted to the nagas by Ananda, Lord Buddha’s closest disciple, and to explain these teachings precisely. But who were the nagas that informed him of these texts hidden in their realm and invited him to travel to their kingdom so that he could return with Sutras to India?
 
Kalachakranet wrote about the origin of the prayer wheel and on this occasion spoke about the land of the Naga King: “Arya Chenrezig predicted to Master Ludrup Nyingpo,18 ‘In the palace of the land of Naga is the Naga King Bodhisattva, who is the owner of a profound wheel of Dharma. By hearing, seeing, touching, or thinking of this wheel, one can swiftly attain liberation from the suffering of the three lower rebirths. If you go and fetch this wheel, the benefits to sentient beings will be enormous.’
“Consequently, Master Ludrup visited the land of the Naga and said to Naga King Bodhisattva, ‘Oh, Naga King Bodhisattva, please pay attention to me. I have come here because Arya Chenrezig prophesied that the benefits to sentient beings will be enormous if I beg from you your profound wheel of Dharma, which can liberate beings from all types of sufferings of lower rebirths just by hearing, seeing, touching, or thinking of it. Kindly give it to me.’
“Naga King Bodhisattva replied, ‘This wheel of Dharma, which has the quality of quickly liberating all transmigrators from the great suffering of the three lower rebirths merely by hearing, seeing, touching, or thinking of it, was kindly given to us in the past by the Buddha Marmed Tse, and has given nagas much happiness, through it many have been led to the grounds and paths of Buddhahood.  This Dharma Wheel is the wheel of the mantra OM MANI PADME HUNG, the essence mantra that Arya Chenrezig received from the Buddhas upon request and which represents the essence of all the qualities of body, speech, mind, and actions of the Buddhas. I shall give this wheel to you. You must place it on or in earth, water, fire, or wind and use it for the sake of Dharma and living beings.’
“The wheel was passed on to Master Nagarjuna together with its instructions for use. Master Nagarjuna brought it to India and later passed it on to the Lion-Faced Dakini. From her the lineage passed through Tilopa, Naropa, Marpa and Milarepa, to Dakpo Lha Je (Gampopa), then to Khampa Yu Se, and so on.” 19
 
Isn’t the jewel all living beings seek an echo of the inner forces of energy when integrated and expended wholesomely? Thrangu Rinpoche taught that Yid Shin Norbu, the “Wish-Fulfilling Jewel,” exists “in the naga or deva realms and gives the owner whatever he or she wants.” Thrangu Rinpoche also told us that the term is used metaphorically,20 illustrated in the account of the “Seven Noble Treasures” that follows.
 
Dr. Peter Della Santina, who translated the Suhrillekha, wrote that Nagarjuna spoke with King Gautamiputra in great depth on morality “that should not be flawed by faults.” Santina described Nagarjuna’s immense insight and compassion and gave a detailed summary of both the Suhrillekha and Ratnavali. A few passages from Santina’s essay: “Nagarjuna mentions the Seven Noble Treasures given by the Buddha to his only son Rahula. The story recounted about the bestowing of this teaching is very interesting.
“Rahula, it is said, was persuaded by his mother on the occasion of his father, the Buddha’s return to Kapilavastu, to go and ask his father for his inheritance. Doubtless, there was a little ranker in this stratagem. The Buddha, however, characteristically changed the entire level of the discussion. The Buddha pointed out the perishable nature of worldly wealth such as houses, gold, silver, and the like and gave to his son instead another inheritance, the Seven Noble Treasures, i.e., faith, morality, giving, study, modesty, humility, and wisdom. Therefore, it is clear that Nagarjuna, notwithstanding his profound knowledge of emptiness, did not hesitate to emphasize the importance of morality in his letters to his friend. (…) The specific injunctions and prohibitions of morality may be formulated, their essence is the same. It is the principle of non-injury, ahimsa. (…) Nagarjuna also asks us to call to mind six objects worthy of recollection. They are the Three Gems - the Buddha, Dharma, and Sangha -, giving, morality and the gods. (…) One may ask, why are the gods particularly recommended by Nagarjuna as objects worthy of recall? Buddhism is, one might think, largely a non-theistic religion, and so it is. The reason is that it is the morality and mental development practiced in former lives by the gods that has brought them to their high station in the world, and therefore, by bringing them to mind, one can remind oneself to practice morality and meditation similar to that once practiced by the gods. (…) Once again, taking his inspiration directly from the words of the Buddha himself, Nagarjuna asks us to avoid six indulgences, which, as he says, result in the loss of one’s good name and rebirth in states of woe. They are gambling, laziness, association with unwholesome friends, alcohol, etc. (…)
“Nagarjuna proceeds to give his friend a lot of sound advice about the conduct of everyday social affairs. He tells the king that persons have to be judged according to both their actions and intentions. In order to make himself clear he uses the simile of mangoes. Some, he says, appear to be ripe, but are in fact green; others appear to be green but are in fact ripe. Yet others appear to be green and are in fact green; while still others appear to be ripe and are indeed ripe. The appearance of the fruit and its actual state of maturity correspond to the actions and intentions of people. One, he says, should endeavour to have friends whose actions and intentions are both wholesome.
“Nagarjuna also displays a keen sense of social consciousness and (…) calls for the blind, the sick, the poor, the homeless, and the crippled to be always provided with food and drink. In other words, Nagarjuna in the 2nd century C.E. called for an extensive system of social welfare to be established by the state. (…) He even concerned himself with the treatment of prisoners. (…) He expresses a concept that only dawned upon western social philosophers at the time of the 18th century so-called ‘enlightenment’ in Europe, i.e., wrong doers should be punished with the sole wish to reform them, not with the wish to exact revenge. Like sons who have gone astray, prisoners should be punished in such a way as to make them once again worthy members of society. (…) The hardest punishment for well-known and hardened criminals, which Nagarjuna is prepared to tolerate, is deportation. (…)
“All of these texts seem to have achieved their objective. They were enormously popular with ordinary practitioners of Buddhism. Even I-tsing, who visited India in the 7th century C.E., reports that the Suhrillekha was on the lips of practically every child throughout the length and breadth of India. (…) It is not surprising inasmuch as the texts have the remarkable characteristic of being able to teach a comprehensive version of Buddhism which is also useful and accessible to the ordinary person like you and me.”21
 
The Rangjung Yeshe Glossary noted that Nagarjuna lived for 600 years, that he erected pillars and stone walls to protect the Bodhi Tree at Bodhgaya and that he constructed 108 stupas. Furthermore, “Having attained realization of Hayagriva,22 he transmitted the lineage to Padmasambhava. (…) He had four principal spiritual sons, Shakyamitra, Nagabodhi, Aryadeva, and Matanga, as well as three close sons, Buddhapalita, Bhavaviveka, and Ashvagosha.”23
 
 
Nagarjuna remembered and offered his life
 
 
Rangjung Yeshe tells us, “Once a young prince, who coveted his father’s kingdom, was told by his mother, ‘Your father’s life is linked to that of Master Nagarjuna, who himself attained eternal life. Therefore, you will never rule the kingdom.’ Not bearing her son’s unhappiness, the queen later added, ‘Nagarjuna is a Bodhisattva. If you ask him for his head, he will give it to you.’ The prince did just that, and Nagarjuna consented to give his head. But although the prince struck with his sword again and again, the master’s neck could not be severed. Nagarjuna said, ‘Once when I was cutting kusha grass, I cut off the head of an insect. The karmic consequences of this act can still affect me and you can easily kill me with a blade of kusha grass.’24 The prince tried and at the first stroke the master’s head fell on the ground. Milk poured out and the severed head spoke, ‘I shall now go to Tushita heaven, but later I shall return in this very same body.’ Afraid, the prince threw the head far away.”25
 
 
Conclusion
 
 
We are invited to participate and realize, as best as we possibly can, the most invaluable instructions that, through Lord Buddha’s inspiration, Noble Nagarjuna summarized in the following praise for the benefit of his pupils living beyond any restrictions of space and time:
 
 
“In Praise of the Dharmadhatu” by Most Noble Nagarjuna
 
 
The phenomena that appear to the mental consciousness, the chief of them all,
Are conceptualised and then superimposed.
When this activity is abandoned, phenomena’s lack of self-essence is known.
Knowing this, meditate on the Dharmadhatu.26
 
 
His Holiness the Gyalwa Karmapa told us at the beginning of these pages, “Tantric Buddhism existed in India at the time in an extremely hidden or secret form and was not made public or accessible to the general Buddhist practitioners. It expanded even more during the time of Saraha, Nagarjuna, and other great Mahasiddhas and finally came to Tibet in full through the blessings of Guru Padmasambhava, Marpa the Great Translator, and many other eminent Indian and Tibetan masters.”27
 
Our Lineage Masters realized and always live according to the few words Padmasambhava used when he spoke about himself approximately 700 years after the life of Nagarjuna: “My realization is higher than the sky. But my observance of karma is finer than grains of flour.”28
 
 
May virtue increase!

8 The six Buddhist universities of ancient India were Nalanda, which was probably built during the reign of King Kumara Gupta (415-455) and therefore founded much later than the historical recordings about Mahasiddha Nagarjuna (yet an earlier, smaller site may have existed), Vikramashila, Odantapuri, Somapura (now in the territory of Pakistan), Jagaddala, and Vallabhi (West India). Odantapuri served as a model for Tibetan monasteries, especially Samye Gompa in Central Tibet. The great universities were destroyed along with other major centres of Buddhism in India when Muslims invaded Bihar and unleashed a period of destruction.

14 Magadha was one of the four main kingdoms of India at the time of Buddha Shakyamuni. The core of the kingdom was that portion of Bihar that lies south of the Ganges, with its capital at Rajagriha. Buddha was born as a Prince of Kapilavastu in Kosala, which had been annexed by the Kingdom of Magadha at that time. Therefore Magadha was the scene of many incidents in his life.
15 Shankara was the great philosopher of non-dualistic Vedanta. - The Dharma Fellowship of His Holiness the Gyalwa Karmapa states,  “Shankara's argument (vide Brahmasutra Sankarabhasya) that elementary particles are actualised in terms of having various qualities, rather than quantities per se, is equally invalid, since difference would still presuppose physical measurement in the final analysis. Shankara's supposed groupings of qualitative particles are thought to combine in order to produce the gross atoms and molecules of material perception and yet, once again, the very singularity of the supposed ultimate building blocks of nature precludes their combination, since to combine they would have to possess 'parts.' A singularity is by definition partless and unitary. (…) It follows that Shankara's analogy of ‘rope and snake" is also naive compared to Arya-Vasubandhu's elephant analogy (…) in introducing his system of Adwaita Vedanta, suggested that the world was like a segment of rope mistaken for a snake. The rope is lying on the ground. Dusk has gathered and it is not easy to see clearly. An observer walking along the road mistakes the old piece of rope for a poisonous cobra and takes fright. In this manner, says Shankara, the world and its suffering is perceived, when the reality is the pure Absolute (Brahman) alone. The world is purely illusion (maya). When the illusion is seen for what it is, just as the snake instantly becomes again the rope that it always has been, so too the world transforms back into Brahman. By this means Shankara posited nonduality (adwaita). This analogy overlooks the dichotomy established by it, of an absolute reality opposed to an absolute illusion, or existence (sat) versus non-existence (asat). Although Shankara and Vasubandhu are pointing in the end to the same final truth, Shankara's ‘languaging’ of the problem falls short of Vasubandhu's. It is the same mistake which Shankara makes in terms of his so called qualitative atoms.” The Cuckoo of Awareness.

16 Thrangu Rinpoche taught, “The middle view of Madhyamaka is sometimes referred to as Prajnaparamita, which means ‘Mother of all Buddhas’ since it is the basis for realization. Only with perfect insight into the transcendent nature of Prajnaparamita - the Sanskrit term that was translated into Tibetan as Shes-rab-kyi-pa-rol-tu-phyin-pa (‘Perfection of Wisdom’) - can freedom from samsara be attained and nirvana be realized. The mother of all Buddhas, i.e., the middle view and perfection of wisdom, is the cause for realization of Buddhahood.“
17 Nagarjuna, in the site: Rangjung Yeshe, April 2006. - The Praise to the Absolute Expanse can be found at the end of this article. - The work “Mulamadhyamakakarika, dBu-ma-rtsa-ba-bshes-rab-shes-bya-wa - The Treatise on the Middle Way” is definitely attributed to Nagarjuna by academia. It explains relative and ultimate truths, proves that nothing arises of its own accord, that nothing is self-existent, and therefore permanence is refuted. Phenomena are explained to be dependent, transient events, rather than having their own inherent nature, and therefore annihilation is refuted. It is said that emptiness should not be taught to those who are not prepared to understand because they may develop negative reactions, but the fundamental goal of Buddhism is to overcome suffering, which is achieved by realizing emptiness that can also be described as the lack of impediment for spatial existents.  – Concerning the works of Nagarjuna, see “Suhrillekha, She-pai-tin-yig - Nagarjuna’s Letter to King Gautamiputra with a Commentary by Sakya Trizin, Jamspal Chophel.” Translated by Dr. Peter Della Santina, Motilal Banarsidass Press, New Delhi, 1978. Other works attributed to Nagarjuna are “Shunyatasabtikarika, sTong-nyid-bduen-chu-pa – Sixty Verses on Emptiness” and “Yukitashashakakarika (?), Rigs-pa-drug-chu-pa – Seventy Verses on Reasoning,” furthermore, “Ratnavali, Rin-chen-teng-wa – The Precious Garland,” which has been translated & edited by Jeffrey Hopkins & Lati Rinpoche, Vikas Publishing House, Delhi, India, 1975. - Although Nagarjuna is said to have lived hundreds of years, the texts have been dated to the first few century C.E.
18 Nagarjuna is called “The Heart, The Essence” in Tibetan, i.e., “The Heart that has power over the nagas.”

24 Kusha grass was used as a ritual seat in earliest Vedic times: “In the Bhagavad Gita it is said that such a seat or asana must be made up of a mat of kusha grass, covered with a deer skin, on top of which a silk cloth must be spread. Why so? Kusha grass is traditionally considered sacred. Besides, it is almost an insect repellent. Insects like white ants might attack wood, but not kusha grass. The hardest of the three materials, i.e., the kusha grass, forms the lowest base of the asana. Deer skin of softer variety and the silk covering is meant to prevent feeling hurt sitting for a long time.” Swami Brahmeshananda, On Asana, in the site: Sriramakrishnamath/magazine, April 2006.

26 Nagarjuna, In Praise of the Dharmadhatu. Translated by Jim Scott, in: Shenphen Osel, vol. 3, no. 2, Oct. 1999, page 1. – Dharmadhatu is “the suchness in which emptiness and dependent origination are inseparable; nature of mind that lies beyond arising, dwelling and ceasing.” Eric Pema Kunsang & Marcia Binder Schmidt, Blazing Splendour, Rangjung Yeshe Publications, Boudhanath, 2005, page 402. Ven. Khenpo Tsultrim Gyamtso Rinpoche explained, „In general, we can know that, of all the phenomena that cause samsara and nirvana, not one of them moves from the expanse of the dharmadhatu. The essential nature of samsara and nirvana is nothing other than the dharmadhatu. Yet, it is the case that we do not realize that; we do not realize the genuine nature of reality. Therefore, we have the confused appearances, the mental afflictions and the suffering that constitute samsara. Because of our ignorance of the dharmadhatu, we go around in samsara.” Khenpo Tsultrim Gyamtso Rinpoche, The Dharmadhatu, in: Bodhi, issue 4, 1999.
