After this comes control of the thoughts, which is the second step, control of the body coming first. Thousands of people have found that they can sit in the postures for hours, but cannot keep their mind still. This has to be learned by degrees. A person cannot control his mind by willing to think of nothing; that will never be possible. First let the mind hold whatever thought interests it, any thought of love, of goodwill - whatever interests it. Check its tendency to jump from one thing to another. When you catch the mind jumping from one thing to another, bring it back and hold it. You must say: I am greater than my mind, my will is greater than my mind, and I will make my mind obey my will.
