Vimalamirti
Upon the advice of Vajrasattva, Vimalamitra went to China and received the complete oral lineage from Shri Singha. Dakinis then told him to go to the Bhasing charnel ground where he received more empowerments, instructions and texts from his old friend Jnanasutra. Later he went to Tibet and became one of the great masters who introduced dzogchen to Tibet. After thirteen years in Tibet he returned to the Five Peaks (Wu-tai Shan) in China where he attained the rainbow body. He vowed to send an incarnation to Tibet every century to continue the Nyingthik teachings
