Ramana Maharshi

M: See the mind. You must stand aloof from it. You are not the mind.
Q: How should we do all this?
M: The lack of the feeling that we are the Self is the root cause of the trouble. Have nothing to do with thoughts, and be, just be. It is the thoughts alone that create the hindrance; they are the trouble. Find out to whom the thoughts occur. As long as you think that a wrong self exists, it will appear to do so, but find out where it arises and it will disappear. Those who have discovered great truths have done so in the still depths of the Self.
