The Practice of Meditation... is very simple; and so very straightforward. Keep the eyes closed. Be with the breath. Just be with the breath. Just be with the natural rhythm of the breath. No mantras whatsoever. No sounds from the mouth whatsoever. Keep the mouth shut.
We all can become like Jesus Christ! We all can become like Mohammed! Each of us can be a Zoraster, or a Buddha, or a Socrates, or a RamanaMaharshi! How Simple.. We have to Meditate! We have to calm our minds!
