I read a book in the mid-1970s. I was told at the time it was an underground book. I don't know what that, means but it sounds like a joke now.
The book was about karma, telekinesis and other mind powers. The main character went to sleep at night and while sleeping traveled out of body and had to try to advance to a higher level of thinking, for example by not interfering when someone was being hurt as this was their karma that needed to be fulfilled so they could move to the next level of existence.
Does any one remember this? I think there was a year date in the title (for example 2010___).
