The Tsekar (White Amitayus) Drubchen is a practice of the five family Buddha Amitayus with the hundred deities. Guru Rinpoche received this practice at the Maratika cave in Nepal with Lhacham Mandarava.
"With dignity, we perceive things as they actually are, and we perceive ourselves as we actually are. This clarity of vision and understanding protects us from the distraction and confusion that ordinarily lead us to question ourselves and our reality. The result is a profound and powerful sense of inner stability. Like a diamond."
Phakchok Rinpoche, Awakening Dignity, Chapter 1: The Mirror of the Heart
