Taken from the teachings of an Indian Spiritual Guru -
Q: Is there an easy way to make an agitated mind relatively quiet and peaceful?
A: "Observation of the breath". Herein our normal breathing activity is observed, merely remaining a witness to the incoming and outgoing breath. No effort is made to control the breath. Our various thoughts are restrained for sometime and the thought flutterings are temporarily controlled; the mind becomes relatively quiet and peaceful.
You ought to try this!
