When one comes to reason out what one should renounce and in what way one should practice renunciation, there is a lesson to be learned: no virtue is a virtue if it is forced upon the one who is incapable of it. A person upon whom a virtue is forced, who is forced to renounce, cannot make the right renunciation. No virtue which gives pain is a virtue. If it gives pain, how can it be a virtue? It is called virtue because it gives happiness; that which takes away happiness can never be a virtue. Therefore renunciation is rightly practiced by those who understand renunciation, and are capable of practicing it.
