"Tomorrow may never come to us. We do not live in tomorrow. We cannot find it in any of our title-deeds. The man who owns whole blocks of real estate, and great ships on the sea, does not own a single minute of tomorrow. Tomorrow! It is a mysterious possibility, not yet born. It lies under the seal of midnight-behind the veil of glittering constellations."

This is a world of good and evil. Wherever there is good, evil follows, but beyond and behind all these manifestations, all these contradictions, the Vedanta finds out that Unity. It says, "Give up what is evil and give up what is good." What remains then? Behind good and evil stands something which is yours, the real you, beyond every evil, and beyond every good too, and it is that which is manifesting itself as good and bad. Know that first, and then and then alone you will be a true optimist, and not before; for then you will be able to control everything.
