Continuing the tradition of recent years, Rinpoche offers to guide us in the purification practice of Vajrasattva. One of the fundamental characteristics of karma is that it grows over time, like a seed capable of yielding a large quantity of fruit. To prevent the growth of negative imprints in our mind, it is necessary to purify it. This is the very purpose of Vajrasattva practice. The recitation of its hundred-syllable mantra, combined with the application of the four opponent powers, allows for the elimination of negative karmas accumulated through body, speech, and mind, and also for the restoration of broken vows and samayas. This intensive practice is open to all, but it is preferable to have received the Vajrasattva initiation and to complete the four daily sessions.
