In the Vajrayana tradition, and especially in the Preliminary Practices, one can meditate on the teacher as Vajrasattva to cleanse all obscurations. "The teacher Vajrasattva embodies the hundred deities in one. He is called 'Vajrasattva, the single deity of the great secret' " [Patrul Rinpoche, in Words of My Perfect Teacher].
We carry many beautiful images, teachings and texts to support your Vajrasattva practice.
