It helps you focus your mind, well lose you your mind and aids in self-realization. Now, I'm not saying that everyone uses for that, in fact most people don't, but that is what I am learning it for.

Also, jeez, I didn't think it up. I researched, practiced, and am succeeding. Is it that hard of a concept to understand? I did tk a few hours ago. Don't tell me it's not real...it's just funny.
