Developing Best Speech
What techniques can we use to develop most excellent speech? We can say prayers, such as, “Great Vajradhara, Tilopa, Naropa, Gampopa” and we can recite mantras like
OM MANI PEDME HUNG
These prayers and mantras show us how to express thoughts which are most noble, which are completely beneficial, pure, and good. Part of our Dharma practice is to study, the reciting of texts, prayers, and mantras which bring about the very excellent training of the best of speech. All of these activities sow the seeds for good and right things in our mind which will afterwards become the basis for the expression of what will benefit ourselves and others. This is perhaps even more important today than it was in the past because we have such powerful means of communication. We should always be aware of the potential of communication and speech to either benefit or harm others.
