Side note on the "mystic flavor" yoga (as oppose to plain "mindfullness meditation" and "yoga for back pains") and other "eastern" spirituality things: I think there's a reason why there are so many initiation ceremonies and tasks that one was/is traditionally put to do before going-off-the-deep-end, and why ancient hindus saw being a yogi as a path for one that was of a certain age and already had a family and proved itself capable of functioning in society -
to weed out anyone with preexisting mental health conditions. You even see this pattern in the story of Buddha's life - he was a socially capable young prince born in a loving family and had no frustrations and most material needs fully satisfied. And also for the zen philosophy attitude of "but don't take these things too seriously" -
to prevent people from actually "drowning" in these mystical visions and loosing any contact with reality.Overall I think that a lot of people would benefit from the occasional mystical perspective on life. It's awesome for creative problem solving! And most people have become a bit too secular and boring. But if they go on and apply the "work hard on it and take it seriously" pattern to spirituality they'll just go and OD on it.
The "westernly refined eastern spirituality" seems as close to the original thing as purified cocaine is to chewed coca leaves: very different concentrations, very different use scenarios. How can it not go wrong for the more psychology sensitive individuals among us?
People should go and read/listen some of Allan Watts' book/recordings. You can try starting with this: https://www.youtube.com/watch?v=8130_-3d3PA . He had some good ideas on how to use an occasional mystical perspective to enrich one's life, without taking it too seriously and completely loosing it. Mind it, I don't agree with most of his ideas, but they are still better than what others are selling.
