Dhamma Verses (Dhammapada, KN 2)

10: The Chapter about the Stick – 138
Asceticism is not enough
A householder went forth, but first has a cottage built for
himself, with provisions stored up, slaves and many requisites
so as to live comfortably; the monks complained to the Buddha
who reproved the monk; in a tiff the monk threw off his robe
and out of spite declared he would go around half-naked; the
Buddha reproved him yet again with this verse.
141. Na naggacar i yā na jaṭā na paṅkā,
nānāsakā thaṇḍilasāyikā vā,
rājo ca jallaṁ ukkuṭikappadhānaṁ,
sodhenti maccaṁ avitiṇṇakaṅkhaṁ.
Not nakedness, matted hair, mud,
fasting, lying on stony ground,
dust, dirt, or striving while squatting,
can purify a mortal who
has not removed uncertainty.
