I have recently started reading this amazingly sacred text by HH Trijang Rinpoche. It is a treasure trove for those of us who are practicing the greatly misunderstood, and oft maligned Dorje Shugden. It is fantastic that this website exists. Thank you for providing us with the information that we all want to know and this text in particular.
This text, for me, is so inspiring because it details the previous rebirths of Tulku Dragpa Gyeltsen, showing clearly that Dorje Shugden arose from a lineage of enlightened masters. Anybody who refutes this text, refutes the authority of Trijang Rinpoche. Refuting Trijang Rinpoche, refutes his teachings, which refutes the teachings that His Holiness the Dalai Lama gives to others. Simple logic in my opinion.
