True religion is not talk, or doctrines, or theories, nor is it sectarianism. It is the relation between soul and God. Religion does not consist in erecting temples, or building churches, or attending public worship. It is not to be found in books, or in words, or in lectures, or in organizations. Religion consists in realization. We must realize God, feel God, see God, talk to God. That is religion.
Swami VivekanandaThe Buddha is not a person but a (state of) realization to which anyone can attain.
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.
