I am a slave of Ramakrishna, who left his work to be done by me and will not give me rest till I have finished it. And oh, how shall I speak of him? Oh, his love for me!

He who is alone is happy. Do good to all, like everyone, but do not love anyone. It is a bondage, and bondage brings only misery. Live alone in your mind - that is happiness. To have nobody to care for and never minding who cares for one is the way to be free.

Business is business, that is, you must do everything promptly; delay and shuffling won't do.

To succeed, you must have tremendous perseverance, tremendous will.

Everything can be sacrificed for truth, but truth cannot be sacrificed for anything.

Every human being has the right to ask the reason, why, and to have his question answered by himself, if he only takes the trouble.

Not one is constant, but everything is changing.
