I have studied with Eva Wong since 2008. She tells us to trust the tea not the teapot— that she is merely the conduit, which has helped me focus on what I want to focus on: the practice itself. Proof, pudding, etc.
I have yet to meet someone I would consider to be a true master, one in whom I could put my complete trust and devotion, nor do I think that is necessary. I have studied with a number of teachers, and in my experience, they are either fairly unrealized, or come with quite interesting personality... quirks.
Having said all that, I would like to meet a true master one day, and I hope I would be able to recognize their mastery. Nominations welcome!
I continue to study with Eva Wong because of the practice itself.
