If you really want the good of others, the whole universe may stand against you and cannot hurt you. It must crumble before your power of the Lord Himself in you if you are sincere and really unselfish.
Swami VivekanandaThose who have succeeded in attaching or detaching their minds at will have succeeded in Pratyahara, which means gathering towards, checking the outgoing powers of the mind, freeing it from the thralldom of the senses. When we can do this, we shall really possess character; then alone we shall have taken a long step towards freedom. Before that, we are mere machines.
Swami VivekanandaAnything that is secret and mysterious in this system of Yoga should be at once rejected. The best guide in life is strength. In spirituality, as in all other matters, discard everything that weakens you. Have nothing to do with it. Mystery-mongering weakens the human brain. It has well-nigh destroyed Yoga, one of the grandest of sciences
Swami Vivekananda
