I know what you're talking about, and I went through 3(!) major episodes of that kind. Of course, in the end I came out a much better person with a lot of weight lifted off of my shoulders.

Also, I was being very conservative with my comment and it is impossible for me to truly highlight my experiences without writing a book about it. I can say that I met a lot of very interesting people, educated and wise people who helped me a lot.

Actually, if you look at the old texts from Hindu Rishis and Swamis who lived throughout India - most of them talk about teachers appearing if you have the correct discipline.

This was my experience.
