Pratyakṣa–Āgama–Ācāra: Doubt, Proof, and the Practice of Dharma (प्रत्यक्ष–आगम–आचारविचारः)
युक्तैयोंगवहै: सद्धिग्रीष्मे पजचतपैस्तथा । मण्डूकयोगनियतैर्यथान्यायं निषेविभि:
yuktair yogavahaiḥ saddhi grīṣme pañcatapais tathā | maṇḍūka-yoga-niyatair yathā-nyāyaṁ niṣevibhiḥ ||
摩诃提婆言：“以能载人趋向瑜伽的正当戒行，当摄心专注而勤修不辍。盛夏炎热之时，卓越的林栖者当行‘五火’之苦行。又当依规恒守哈他瑜伽所传之‘蛙式’（maṇḍūka-yoga），凡所受用与取舍，皆须合乎公正与端正之道。”

Educational Q&A
Maintain one-pointedness and pursue yoga through regulated disciplines; undertake appropriate austerities (like pañcatapas for a forest-dweller) and consume or use things only in a manner consistent with nyāya—propriety, justice, and right measure.
Śiva (Mahādeva) is instructing on ascetic-yogic conduct: he outlines concrete practices—summer pañcatapas, regulated maṇḍūka-yoga—and frames them within an ethical rule of right and measured enjoyment (yathā-nyāyam).
