It is excellent to know what the genuine Dharma is. However, if one does not meditate, the ultimate result will not be obtained, so practice is very important. Further, rather than practicing alone in a solitary place, it is better to practice in a group. Repa Shiwa said, "The basis of virtuous activity is compatible Dharma friends." Through the encouragement of Lamas and friends who truly follow the Dharma, one's faith and diligence grow and one's laziness and discouragement are turned around.
