Drime Shenyen), an 8th century Indian adept, is key to the history of Tibetan Buddhist Dzogchen
practice. He lived equally in China
, but was known as the "Sage of Kashmir". According to tradition, he was born in Western India
and travelled to China
to become a disciple of Shri Singha
. He was also a student of Buddhaguhya
. Upon his return to India, he was invited to Tibet
by emissaries of King Trisong Detsen
where he established himself as a teacher and translator of Dzogchen texts and an important teacher within what centuries later came to be known as the Nyingmapa
Vimalamitra united two disparate aspects of the Nyingtig teachings: the explanatory lineage with scriptures, and the hearing lineage without scriptures and elementally concealed them as terma to be revealed as the Vima Nyingtig (bi ma snying thig) and as the Secret Heart Essence of Vimalamitra (bi ma'i gsang ba snying thig).
Vimalamitra also translated, together with Ma Rinchen Chok, important Nyingmapa texts such as the Guhyasamaja Tantra and the Guhyagarbha (Tib., gSang-ba snying-po, "The Secret Heart", or "Essence of Secrets").
Vimalamitra, according to the Nyingma tradition, was a pupil of Buddhaguhya and Lilavajra, as was Vairotsana who received the Mahayoga (Māyā-jāla Cycle) transmission from Buddhaguhya.
One tradition of Dzogchen was directly transmitted to Vajrasattva, an aspect of the Sambhogakaya, to Garab Dorje (b. 55 CE), the Nirmanakaya. Garab Dorje transcribed this teaching which he transmitted to his disciple Manjushrimitra. Mañjushrīmītra classified the teaching into three cycles:
- Semde (mind class/cycle);
- Longde (space class/cycle); and
- Mengagde (oral instruction class/cycle), and this classification determined the exposition of the Dzogchen teachings in the following centuries. Mañjushrīmītra’s student Shrisimha re-edited the oral instruction class/cycle, and in this form the teaching was transmitted to Jñānasūtra and Vimalamitra (sometimes Vimilamitra). Vimalamitra took the Mengagde disciplic teaching to Tibet in the 8th Century.
Vimalamitra was responsible for authoring the Vima Nyingthig
or 'Secret Heart Essence of Vimalamitra'. This cycle of texts belongs to the Secret Instruction or Menngagde
division of Atiyoga
In regards to the Nyingtig Yabshi, Vimalamitra united the two aspects of Innermost Unexcelled Section — the explanatory lineage with scriptures and the hearing lineage without scriptures — and concealed them to be revealed as the Nyingtig teachings Vima Nyingtig.
