Swami Vivekananda

 The Hindu concentrated on the internal world, upon the unseen realms in the Self, and developed the science of Yoga. Yoga is controlling the senses, will and mind. The benefit of its study is that we learn to control instead of being controlled. Mind seems to be layer on layer. Our real goal is to cross all these intervening strata of our being and find God. The end and aim of Yoga is to realise God. To do this we must go beyond relative knowledge, go beyond the sense-world. The world is awake to the senses, the children of the Lord are asleep on that plane. The world is asleep to the Eternal, the children of the Lord are awake in that realm. These are the sons of God. There is but one way to control the senses—to see Him who is the Reality in the universe. Then and only then can we really conquer our senses
