Vajrasattva is a bodhisattva in the Mahayana, Mantrayana/Vajrayana Buddhist traditions. In Chinese Buddhism and the Japanese Shingon tradition, Vajrasattva is the esoteric aspect of the bodhisattva Samantabhadra and is commonly associated with the student practitioner who through the master's teachings, attains an ever-enriching subtle and rarefied grounding in their esoteric practice. In Tibetan Buddhism, Vajrasattva is associated with the sambhogakāya and purification practice.
