Vajrasattva
Vajrasattva [Skt.] (Tib. dorje sempa; rdo rje sems dpa’) - The sambhogakaya buddha Vajrasattva is the sovereign of all the buddha families and mandalas. The lineage of Dzogchen is traced from the dharmakaya Samantabhadra to the sambhogakaya—the five buddha families and Vajrasattva, who are Samantabhadra’s own self-reflection. This is the mind direct transmission.
