I've been euphoric manic for much of my life, and I definitely felt at one with the world, with the universal, when in such a state. I felt there was no boundary between me and nature and the cosmic reality of life. The most profound experience I had was once when I was riding my bike the clouds opened up and a shaft of light seemed to fall upon me. I blacked out and woke on the side of the road, sure that I had been touched by the finger of God. Looking back, it was a bout of extreme euphoric mania. However, it stayed with me as a profound religious experience for a long, long time.
