Go to a crystal healer with a problem of some sort - and see for yourself.
Seeing is believing...believe no one if you are the skeptical type.
"Prepare yourself for the coming astral journey of death by riding daily in a balloon of divine perception.
Through delusion you are perceiving yourself as a bundle of flesh and bones...Meditate unceasingly,
that you quickly behold yourself as the Infinite Essence" ~~Lahiri Mahasaya, the guru of Yogananda's guru.
