पञ्चाग्निर्धूमपो वा स्यादुष्मपः सोमपो ऽपि वा / पयः पिबेच्छुक्लपक्षे कृष्णापक्षे तु गोमयम् / शीर्णपर्णाशनो वा स्यात् कृच्छ्रैर् वा वर्तयेत् सदा
pañcāgnirdhūmapo vā syāduṣmapaḥ somapo 'pi vā / payaḥ pibecchuklapakṣe kṛṣṇāpakṣe tu gomayam / śīrṇaparṇāśano vā syāt kṛcchrair vā vartayet sadā
「五火」（パンチャーグニ）の苦行を行うことも、煙を「飲む」ようにして生きることも、熱い蒸気を「飲む」ことも、さらにはソーマにより身を支えることもある。白分（シュクラ・パクシャ）には乳を飲み、黒分（クリシュナ・パクシャ）には牛糞を取る。あるいは落ちて枯れた葉を食として生きる。かくして常に、厳しい贖罪の行（クリッチャラ）によって身を保つべきである。

FAQs
Indirectly: it emphasizes purification through restraint and tapas, preparing the practitioner’s body-mind for steadiness and insight, which the Purāṇa elsewhere links to realizing the Self beyond impurities.
It highlights ascetic disciplines (tapas) and kṛcchra-type observances—regulated diet and endurance-based vows—which function as foundational yama/niyama-style practices supporting concentration and higher contemplative yoga.
By presenting tapas and purity as universal dharmic means rather than sectarian markers, it supports the Kurma Purana’s broader Shaiva–Vaishnava synthesis: the same disciplines serve devotion and realization oriented to either Śiva or Viṣṇu as the one supreme.
