Why do you ask anybody else's view about ermazi? The fact itself tells us that you are hesitating about something, not believing yourself as you looked like. I don't think what other persons say could become what you think. So, find the answer by your self.
As you ask in this forum, I'd like to talk my opinion for a response. Ermazi maybe the best teacher in the present world to explain Buddhism in plain words other than 名相. He made great effort in talking online to propagate Esoteric Buddhism, Zen and Pureland Buddhism, which is the very reflection of his 菩提心。
