There cannot be self-restraint in the absence of desire: when there is no adversary, what avails thy courage? Hark, do not castrate thyself, do not become a monk: chastity depends on the existence of lust.
RumiMy dear soul, flee from the worthless, stay close only to those with a pure heart. Like attracts like. A crow will lead you to the graveyard, a parrot to a lump of sugar.
Rumi
