An explanation of meditation by S. N. Goenka:

“Don’t try to control the breath or to breathe in any particular way. Just observe the reality of the present moment, whatever it may be. When the breath comes in, you are just aware — now the breath is coming in. When the breath goes out, you are just aware — now the breath is going out. And when you lose your focus and your mind starts wandering in memories and fantasies, just remain aware — now my mind has wandered away from the breath.”
