Vimalamitra

One of the most prominent historical figures in the Dzogchen lineage, and also in Blazing Splendor, is the amazing master Vimalamitra, a direct disciple of Shri Singha. When Padmasambhava arrived in Tibet, he perceived that the time was ready for Vimalamitra to teach the Great Perfection, and therefore bestowed his own lineage of Heart Essence upon only a few worthy disciples. The wisdom dakini Yeshe Tsogyal then concealed his teachings in the form of terma treasures for future generations. Padmasambhava’s profound hidden treasures containing his instructions on the Great Perfection are therefore primarily found among the revelations of the major tertön masters who have appeared over the centuries since the fifty-five years and six months Padmasambhava spent among the snowy ranges of Tibet.
Vimalamitra's lineage, however, was continued. I would like to introduce Wellsprings of the Great Perfection, (a new book from Rangjung Yeshe Publications), which contains many of his songs, excerpts from the Heart Essence of Vimalamitra and many other references. The first excerpt describes the mind transmission of the conquerors and the twelve Dzogchen buddhas, among whom Buddha Shakyamuni is the twelvth. Here is a record of his meeting with Shri Singha:

It was about then that the son of the king Dhahena Chadu and his wife Singha Shipitika, a monk known as Vimalamitra who was learned in the five topics of knowledge, yearned deeply to know the essential nature. He met Shri Singha and requested the meaning of the realized state, who then bestowed it in full and condensed the essential meaning for him in song:

Five poisons, unrejected, are the five great wisdoms,
While samsara, unrejected, is a timeless, perfect purity.
And once you realize your mind itself is buddha,
There is no state to realize apart from this awakened mind.

On hearing this, Vimalamitra understood the basic intent and then expressed his realization:

A spacious vast is dharmata, ungrasped by thought.
This space of mind itself defies imagination.
Within awakened mind which is no object to conceive,
The basic nature is not gained through cultivation.
Not wrought by meditation, timeless, empty, not apart,
The training is this sameness free of thinking.
