Yoga is the cessation of the movements of the mind. Then there is abiding in the Seer's own form.
PatanjaliJust as the pure crystal takes color from the object which is nearest to it, so the mind, when it is cleared of thought-waves, achieves sameness or identity with the object of its concentration.
PatanjaliWhere the heart is full of kindness which seeks no injury to another, either in act or thought or wish, this full love creates an atmosphere of harmony, whose benign power touches with healing all who come within its influence. Peace in the heart radiates peace to other hearts, even more surely than contention breeds contention.
