Jīva–Ātman Inquiry; Kṣetrajña Doctrine; Karma-based Varṇa; Four Āśramas and Sannyāsa Discipline
य ऊष्मभाव आग्नेयो वह्निनैवोपलभ्यते । अग्निर्जरयते चैतत्तदा जीवो निरर्थकः ॥ २ ॥
ya ūṣmabhāva āgneyo vahninaivopalabhyate | agnirjarayate caitattadā jīvo nirarthakaḥ || 2 ||
जो ऊष्मा-भाव अग्निमय है, वह अग्नि से ही जाना जाता है; और वही अग्नि इस देह को जरा (क्षय) में ले जाती है। तब यदि जीव केवल ऊष्मा-रूप माना जाए, तो वह निरर्थक ठहरेगा।
Sanatkumara (teaching Narada in the Moksha-Dharma dialogue)
Vrata: none
Primary Rasa: shanta
Secondary Rasa: bibhatsa
It teaches viveka (discernment): bodily warmth and life-signs belong to the fire-element and are impermanent; therefore liberation requires not mistaking the jīva for a mere bodily function.
By weakening body-identification, it supports pure devotion: when one stops equating the self with perishable heat/prāṇa, the mind can turn toward the eternal Lord as the true refuge beyond the elements.
A basic tattva-viveka aligned with Vedic cosmology: recognizing agni/tejas as the principle behind bodily heat, useful for contemplative analysis (not a ritual instruction, but a practical aid for self-inquiry).
