do you have any reference for the above statement about Kyabje Pabongkha Rinpoche?
Please do not be so quick to criticize Je Pabongkha, as many Gelugpas lineages come through Pabongkha, and many Gelugpas are practising sadhanas/six session yoga written by Pabongkha himself.
I think Pabongkha's letters to Chinese general opens him to many many criticisms, thats historical fact, also the rewriting of dakini sadhanas and six yogas as you mention, and he did that by himself, for himself without any help from members here.
with all that, then when one understands the whole picture, his beloved gyalpo spirit worship etc, one should look objectively at all his activity and ask if it is really worthy of some naive fanboy worship?
i have no answers to give, only questions to ask.
