Since this thread is to discuss Analayo’s critique of Ingram, I won’t venture into all the doctrinal differences and details regarding Indo-Tibetan Buddhist tantra here. If you want to have this conversation, you can start a new thread, or you can do your own research on this tradition before dismissing it out of hand by name dropping two controversial figures. How would you like it if someone totally dismissed the entirety of Theravada by citing Dhammakaya leaders, for example?
Oh and FYI, Kungley gave up his robes so was not a monk during his travels. Trungpa also became a layperson and got married etc. Neither claimed to be arahants.
