Oh, that was because of the book, I think
And I did have rather strange experience with Bhagavad-Gita, too. While behind shrooms (high dosage!) I decided to look at Gita I had at home. Frankly just to watch colors (cover was very bright) and how they would change. Ha! Imagine my surprise when after this "colors trip" I just immediately came back to Earth in just a few seconds!!! Trip cancelled!!! I could feel going back to my body at the speed of light thru different realms untill I was totally back here. Strange episode...

Or, may be, Krishna just saved my "astral body" from something unpleasant?
