Manushya (man) is a being with Manas (mind); and as soon as his thinking power goes, he becomes no better than an animal.
Swami VivekanandaIt is too often believed that a person in his progress towards perfection passes from error to truth; that when he passes on from one thought to another, he must necessarily reject the first. But no error can lead to truth. The soul passing through its different stages goes from truth to truth, and each stage is true; it goes from lower truth to higher truth.
Swami VivekanandaThe same fire that cooks a meal for us may burn a child, and it is no fault of the fire if it does so; the difference lies in the way in which it is used.
Swami VivekanandaChange is always in regard to something which does not change, or which changes relatively less.
