Just Be Happy
What is the cause of passions? Desire to be happy or enjoy pleasure. Why does the desire for happiness arise? Because your nature is happiness itself and it is natural that you come into your own. This happiness is not found anywhere besides the Self. Do not look for it elsewhere. But seek the Self and abide therein.
Still again, that happiness which is natural is simply re-discovered, so it cannot be lost. Whereas the happiness arising from other objects are external and thus liable to be lost. Therefore it cannot be permanent and so it is not worth seeking.
