Jīva–Ātman Inquiry; Kṣetrajña Doctrine; Karma-based Varṇa; Four Āśramas and Sannyāsa Discipline
न नश्यते सुसूक्ष्मत्वाद्यथा ज्योतिर्न संशयः । प्राणान्धारयते ह्यग्निः स जीव उपधार्यताम् ॥ २५ ॥
na naśyate susūkṣmatvādyathā jyotirna saṃśayaḥ | prāṇāndhārayate hyagniḥ sa jīva upadhāryatām || 25 ||
เพราะละเอียดอย่างยิ่ง จึงไม่สูญสิ้น—ดุจแสงสว่างไม่สูญสิ้น; ข้อนี้ไร้ข้อกังขา ไฟแลเป็นผู้ค้ำจุนปราณะทั้งหลาย; เพราะฉะนั้นพึงรู้หลักนั้นว่าเป็นชีวะ (ญาณชีวิต)॥๒๕॥
Sanatkumara (teaching Narada in Moksha-Dharma dialogue)
Vrata: none
Primary Rasa: shanta
Secondary Rasa: adbhuta
It asserts the imperishability of the living principle due to its subtle nature, using light as an analogy, and points to the life-sustaining function (support of prāṇa) as a mark of the jīva—supporting a Moksha-Dharma emphasis on discerning the Self beyond gross decay.
While framed as jñāna-oriented discrimination (viveka), it supports Bhakti by strengthening conviction that the true self is not destroyed; such steadiness reduces fear and attachment, making single-pointed devotion and surrender to the imperishable reality (ultimately Vishnu) more stable.
No specific Vedāṅga technique is taught; the verse uses a classical Upanishadic-style analogy (dṛṣṭānta) and precise terminology (prāṇa, agni, jyotis, jīva) to train philosophical discernment rather than ritual, grammar, or astrology.
