Dhamma Verses (Dhammapada, KN 2)

21: The Miscellaneous Chapter – 257
What is to be done
The monks of Bhaddiya were very keen on decorating their
shoes, and wearing shoes of many different and fancy kinds;
when the monks reported this matter to the Buddha he laid
down rules about footwear, and then taught them with these
verses.
292. Yaṁ hi kiccaṁ tad-apaviddhaṁ, akiccaṁ pana kay i rati,
unnalānaṁ pamattānaṁ, tesaṁ vaḍḍhanti āsavā.
That to be done is rejected,
what is not to be done is done,
for the insolent, the heedless,
their pollutants only increase.
293. Yesañ-ca susamāraddhā niccaṁ kāyagatā sati
akiccaṁ te na sevanti, kicce sātaccakārino,
satānaṁ sampajānānaṁ, atthaṁ gacchanti āsavā.
But those who always properly
undertake body-mindfulness
don’t practice what’s not to be done,
persisting in what’s to be done,
for the mindful, fully aware,
the pollutants are laid to rest.
