Net of the Illusory Display: The Root Sadhana from the Heart-Essence of the Deathless Lake-Born Vajra
By Jamyang Khyentse Wangpo
In 1848, at the age of twenty-eight, Jamyang Khyentse Wangpo had a vision in which he was blessed by Guru Rinpoche, who then dissolved into his heart. As a result, the root practice of Guru Tsokye Nyingtik, the Heart-Essence of the Lake-Born Guru, arose in Khyentse Wangpo’s mind, and he immediately wrote down its activity manual.
