Renunciation does not necessarily mean cutting off one's hair or wearing robes. It means letting go of ideas and hopes that the mind wants to grasp, to keep, to investigate. The mind always wants to have more. If it cannot get more, it makes up fantasies and projects them upon the world. All this will never bring true satisfaction and inner peace, which can only be won by renunciation. "Letting go," the fading away of desire, is a key element of the Buddhist path.
