Restriction: A monk undertaking this vow must wash daily. He must change into fresh
clothes daily or shortly after his robes become dirty. His appearance
must be kept immaculate, including either neatly braiding or shaving off
his hair (and, for male monks, maintaining a clean-shaven face). His
vow forbids him from willingly touching the filthy, diseased, dead, or undead (though he may attempt to cleanse or heal those suffering from disease),
though using manufactured weapons to attack these creatures is allowed.
Benefit: A monk with this vow increases his ki pool by 1 ki point for every 5 monk levels (minimum +1).
