I'm not claiming evidence, Richard. You are. That's the difference between us. You don't have any evidence. Neither do I, but I'm not pretending I do. ;-)

I consider it highly probable that chakras exist, as expostulated in many Eastern teachings. I do not claim to have definitive evidence of it, I just consider it highly probable, that's all. My consideration is based upon familiarity with the subject and with people who have experience to to upon.

I have far better reason to think chakras exist than you do to think they do not, and I am not so ready as you are to deny another human being's personal experiences merely on the basis of my own prejudice and prior beliefs.
