141-142:

Neither nakedness nor matted hair
nor mud nor the refusal of food
nor sleeping on the bare ground
nor dust & dirt nor squatting austerities
cleanses the mortal
who's not gone beyond doubt.
If, though adorned, one lives in tune
with the chaste life
-- calmed, tamed, & assured --
having put down the rod toward all beings,
he's a contemplative
        a brahman
        a monk.
