It 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 VivekanandaAs soon as a man stands up and says he is right or his church is right, and all others are wrong, he is himself all wrong. He does not know that upon the proof of all the others depends the proof of his own. Love and charity for the whole human race, that is the test of true religiousness. I do not mean the sentimental statement that all men are brothers, but that one must feel the oneness of human life.
Swami Vivekananda
