Meditation is sticking to one thought. That single thought keeps away other thoughts; distraction of mind is a sign of its weakness; by constant meditation it gains strength.
Concentration of the mind is in a way common to both Knowledge and Yoga. Yoga aims at union of the individual with the universal, the Reality. This Reality cannot be new. It must exist even now, and it does exist.
All bad qualities centre round the ego. When the ego is gone, Realisation results by itself. There are neither good nor bad qualities in the Self. The Self is free from all qualities. Qualities pertain to the mind only.
