Khenpo Tsultrim Gyamtso Rinpoche

He left home at an early age to train with Lama Zopa Tarchin, who was to become his root guru.

[2] During the 1959 Tibetan uprising Rinpoche fled Tibet, leading a group of Buddhist nuns over the Himalayas to safety in Bhutan.

He subsequently went to northern India, where he spent the next nine years at the Buxa Duar Tibetan Refugee Camp.

At the direction of the Karmapa, he subsequently settled in Bhutan, where he built a nunnery, retreat center, and school.

Hookham explains the Shentong position, referring to Khenpo Tsultrim's Progressive Stages of Meditation on Emptiness.
