Brother reached enlightenment and dispatched all his worldly desires only to instantly regress because bro really wanted to get some handfuls of the booba.
Actually, it seems like his powers are fueled by his desires, rather than removing the desires - he became stronger because he was being lustful, not because he ignored those urges. So he really shouldn't need to abstain and live such an Ascetic life...
Or does he lose his powers the moment he loses his virginity or something?
