Vajrasattva Buddha is one of the main deities of Vajrayana Buddhism. In Tibetan and Nepalese Buddhism it is considered as the sixth Dhyani Buddha, as the priest of the Five-Dhyani Buddhas (Pancha Buddhas). Followers or devotees worship him in a secret way. The lessons are not revealed to those who do not follow the path of Vajrayana Buddhism. In a way, it does not have easy access. One has to fulfill the norms of Vajrayana Buddhism.
Vajrasattva Buddha rupa has two forms, one is single and another is YabYum (Tibetan Form – it comes with the consort or partner). This Dhyani Buddha wears all the rich jewelry gold or silver ornaments with precious or semi precious stones carved in them , rich dresses and crown decorated again with precious metals and stones. These ornaments are typically made in Lalitpur, Nepal. Check here for Newari Tibetan Ornaments and ritual items.
