The first time I completely quieted my mind totally freaked me out. I panicked so bad I immediately jumped out of the meditation. It took me about two months to go back in and revisit the experience.
After a while I realized that I had truly experienced Ohm - that great emptiness which is all things. I won't lie - it still unsettles me a great deal and it's not someplace I play regularly. I'm not afraid of it anymore, but it's not something I can wrap my head around and that bothers me.
Guess that's one of my biggest failings - I still think too much. At least that's what I'm told.
