Guhyasamaja tantra

The Guhyasamaja is an important tantra in Vajrayana Buddhism, which focuses on a form of the buddha Akshobhya called Akshobhyavajra, also known as Guhyasamaja. Like other Highest Yoga Tantras, the Guhyasamaja tantra uses transgressive imagery of wrathful deities, charnel grounds, and sexual union.
