Yup, can totally relate to the Kundalini experience which I discovered on Google when I experienced things similar, but more centered around the sacral chakra for me. Astral projection type “flying” but not really, feeling when I fell asleep. Joining into a big ball of light and sensation of complete well-being.
The story of the Guru….well there’s the documentray about Bikram on Netflix now and when I lived in Salt Lake the same with the zen Buddhist leader, tale as old as time.
Good read!
