Sri Ramakrishna's purity was that of a baby. He never touched money in his life, and lust was absolutely annihilated in him. Do not go to great religious teachers to learn physical science, their whole energy has gone to the spiritual. In Sri Ramakrishna Paramahamsa the man was all dead and only God remained; he actually could not see sin, he was literally "of purer eyes than to behold iniquity". The purity of these few Paramahamsa (Monks of the highest order) is all that holds the world together. If they should all die out and leave it, the world would go to pieces. They do good by simply being, and they know it not; they just are. . .
