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.
Swami VivekanandaIn Tibet there is no marriage, and there is no jealousy, yet we know that marriage is a much higher state. The Tibetans have not known the wonderful enjoyment, the blessing of chastity, the happiness of having a chaste, virtuous wife, or a chaste, virtuous husband. These people cannot feel that. And similarly they do not feel the intense jealousy of the chaste wife or husband, or the misery caused by unfaithfulness on either side, with all the heart-burnings and sorrows which believers in chastity experience. On one side, the latter gain happiness, but on the other, they suffer misery too.
