A man can reach the roof of a house by stone stairs or a ladder or a rope-ladder or a rope or even by a bamboo pole. But he cannot reach the roof if he sets foot now on one and now on another. He should firmly follow one path. Likewise, in order to realize God a man must follow one path with all his strength. But you must regard other views as so many paths leading to God. You should not feel that your path is the only right path and that other paths are wrong. You mustn't bear malice toward others.

p. 514 - The Gospel of Sri Ramakrishna (1942)
