The third step is the hardest and yet is the easiest when learned. It is control of mind. Train the mind always to be loving and kind and to see the best in others. In yourself, see the slightest flaw and ruthlessly correct it. Let nothing escape the eye of the mind.
Concentration is the first step toward conquering the mind.
Learn to concentrate on one thing at a time, for one-pointedness is necessary. Do one thing well. Think a thought through to its culmination. This leads to meditation. Now the pupil is entering the outer portals of God.
