Uv33:1
na nagacaryā na jaṭā na paṅkā no 'nāśanaṃ sthaṇḍīlaśāyikā vā |
na rajomalaṃ notkuṭukaprahāṇaṃ śodheta martyaṃ hy avitīrṇakāṅkṣaṃ ||

Uv33:1 / Not going naked, nor matted hair, nor mud, nor fasting, nor lying on bare ground, / nor the stain of dust, nor the exertion of squatting would purify a mortal who has not crossed over doubt.
