Renunciation born of Divine Realisation, not born of frustration, not born of an escapist attitude, not born of defeatism, but born of an insight into the nature of things, a clear understanding of the nature of life and the wisdom of existence in its completeness. This is the source of Vairagya or renunciation. You do not want anything, not because you cannot get things, but because you have realised the interconnectedness of things, and the unity of all purpose in consciousness. All desires get hushed, sublimated and boiled down to the divine Being only when this realisation comes. God does not possess things.
Possession is a relationship of one thing with another thing.
But, God is super-relative. Anything that is related to something else comes under the category of relative. God is not related to anything else, because He is All-comprehensive. And, thus, in His all-comprehensive Absoluteness, which is height of wisdom conceivable, there is also the concomitant character of freedom from the consciousness of externality, and therefore, as a corollary, freedom from attachment to anything. He does not practise self-control.
