What's the benefit of renunciation?

What's the benefit (ānisaṁso) of renunciation? As in, for example, "*... he gave a progressive discourse, that is, a talk on giving, behaving, and heaven; he revealed the drawback, degradation, and defilement of sensuality and the benefit of renunciation...*". I would say it's less excitement, a more serene and settled heart, a clearer mind, a better, more refined satisfaction. What do you think?
