The denial of the not-Self or the renunciation of the universe means that the Self is not helped by any external agency and it has to save itself through itself. It also means that previous to knowledge, i.e., when the Self appeared to be entangled in the not-self, it was in bondage, as it were, but now because of disentanglement it saves itself and protects itself and is dependent on itself. Because the Self is permanent its independence also is permanent. It is a law that the greater the renunciation, the greater is the joy experienced because of the absence of desires. The wealth does not belong to anyone.
All possessions are perishable.
Therefore, there is no need of coveting anything. Only the knowledge that the Self is all, the Lord of all, should be acquired and everything else should be renounced. Everything is the Atman and, hence, there is no value in desiring anything. As other than the Atman nothing is, nothing can be desired or loved. Do not wish to be reborn in any kind of body, and aspire for liberation alone.
