Vajrasattva

the Buddha of primordial purity is dedicated to the purification of negativities. 

Vajrasattva is an important figure in the tantric Buddhism of the Newar People of the Kathmandu Valley. He represents the ideal guru, and he is frequently invoked in the guru maṇḍala, the foundational ritual for all other Newar Buddhist rituals and the daily pūjā for Newar priests (vajrācāryas).
