Their blind faith demonstrates one of the dangers of religion: the dissolution of the ego can, if accompanied by the dissolution of the critical intellect, can result in abject subjugation to another person’s ego, an ego that may have a hidden and unpalatable agenda'.
True. The potential for the traditional and legitimate teachings on guru-yoga to be abused and become cultish is great. Caveat emptor--in spades!
The guru-yoga teachings are designed for the ideal scenario where the teacher is fully enlightened. The fact that there can be ANY expectation of such a scenario is absolutely astounding to me. Evidently it is EXPECTED to happen on some sort of regular basis. But as we all know, in practice that scenario is actually very rare. So for most of us we must engage in a type of double-think. 99.99% of our teachers will NOT be fully enlightened, so how to see them as such?
My suggestion, and I support this with zero authoritative reference, is to see the teacher as a mixture of enlightened and unenlightened. So far so good. As long as they have lineage and the authority to teach, that's a reasonably safe bet. But enlightenment has an absolute quality to it, kinda like being "a little bit pregnant". So if we have a teacher with meager realization, that's still the realization of a Buddha, only it is covered in dross. So in the guru-yoga of seeing everything the teacher does as pure, we might choose to mentally distill out the dross and affirm the essential. It helps a lot to do this if you have confidence in the lineage. You can see see the person as being flawed, but the teachings as being perfect, thus overcoming your own samsaric mind's limitation of finding fault in everything--which is the point. And of course it is excellent training for when you do finally find a teacher that is fully enlightened. That makes thugs a lot easier.
I say all this with great hesitation. I'm not a Dharma teacher. What I've said is based on my own ignorance, and therefore a corruption of Dharma. Anybody that sees value in it should run it by their own lama for verification.
