People have been putting down this system of meditation since it began- over 5,000 years. That's nothing new and certainly nothing to bother thinking about NOW. What year is this?
Christ himself was a master of energy, prana, the Holy Spirit etc. He would heal people by moving this energy through them.
This is the meditation that the Self-Realization Fellowship, founded by Paramansa Yogananda, teaches.
Depock Chopra actually DOES this meditation you warn people about.
This just goes to show that humans can take anything, ANYTHING at all and turn it into a scarecrow.
It's just a vain attempt at controlling people by making them afraid.
Luckily, whenever people are warned about something, that actually arouses curiousity in them about it and they give it a shot. Especially if the "preacher" is uptight and negative, they're just begging to be rebelled against, even if only for fun.
These sites make meditation almost seem NAUGHTY, don't they? I don't know what it is, I almost feel like forcing prana up and down my spine more now than ever before. Maybe this will catch on and kids will start meditating to rebel against their parents instead of drinking or smoking or "huffing" or whatever it is they do.
