After Ngulchu Dharmabhadra and before Phabongkha Rinpoche, did
Yangchen Drubpay Dorje and
Khedrub Tendzin Tsondru rely on Dorje Shugden?
Update: Just found
Khedrub Tendzin Tsongdru (aka Namkha Tenkyong) on the Dorje Shugden History website (
http://www.dorjeshugdenhistory.org/among-shugden-texts-1799.html), but still wondering about
Yangchen Drubpay Dorje.
