Jiva (individual soul) is the conscious ruler of this body, in whom the five life principles come into unity, and yet that very Jiva is the Atman, because all is Atman.
Swami VivekanandaEvery successful man must have behind him somewhere tremendous integrity, tremendous sincerity, and that is the cause of his signal success in life. He may not have been perfectly unselfish; yet he was tending towards it. If he had been perfectly unselfish, his would have been as great a success as that of the Buddha or of the Christ. The degree of unselfishness marks the degree of success everywhere.
