Sutta Nipata Chapter 2: The Minor Chapter - Culavagga

251. Neither by no fish and meat, nor by fasting,
neither by nakedness, nor by shaven-head;
neither by matted locks, nor being caked in mud,
neither by rough antelope hide, nor by devotion to fire worship;
or even those in the world, who mortify themselves in many ways for the immortal,
neither by incantation and fire oblations, nor devotion to sacrifices and seasonal ascetic practices,
can purify mortals, who have not crossed over doubt.

251. na macchamaṃsaṃ nānasakattaṃ,
na naggiyaṃ na muṇḍiyaṃ jaṭājallaṃ;
kharājināni nāggihuttassupasevanā vā,
ye cāpi loke amarā bahū tapā;
mantā'hutī yaññamutūpavesanā,
sodhenti maccaṃ avitiṇṇakaṅkhaṃ.
