The secret of karma yoga which is to perform actions without any fruitive desires is taught by Lord Krishna in the Bhagavad-Gita.

See Christ, then you are a Christian; all else is talk.

If you have infinite patience and perseverance, success is bound to come. No mistake in that.

If you can think that infinite power, infinite knowledge and indomitable energy lie within you, and if you can bring out that power, you also can become like me.

Everything is ended if you forgive and forget.

We are ever free if we would only believe it, only have faith enough. You are the soul, free and eternal, ever free, ever blessed. Have faith enough and you will be free in a minute.

How do you know what possibilities lie behind that degradation on the surface? You know but little of that which is within you. For behind you is the ocean of infinite power and blessedness.
