U.G Krishnamurti From : The Mystique of Enlightenment

 You can never understand the tremendous peace that is always there within you, that is your natural state. Your trying to create a peaceful state of mind is in fact creating disturbance within you. You can only talk of peace, create a state of mind and say to yourself that you are very peaceful -- but that is not peace; that is violence.

So there is no use in practicing peace, there is no reason to practice silence. Real silence is explosive; it is not the dead state of mind that spiritual seekers think. "Oh, I am at peace with myself! There is silence, a tremendous silence! I experience silence!" -- that doesn't mean anything at all. This is volcanic in its nature: it's bubbling all the time -- the energy, the life -- that is its quality. You may ask how I know. I don't know. Life is aware of itself, if we can put it that way -- it is conscious of itself.
