न नश्यते सुसूक्ष्मत्वाद्यथा ज्योतिर्न संशयः । प्राणान्धारयते ह्यग्निः स जीव उपधार्यताम् ॥ २५ ॥
na naśyate susūkṣmatvādyathā jyotirna saṃśayaḥ | prāṇāndhārayate hyagniḥ sa jīva upadhāryatām || 25 ||
لِشِدَّةِ لُطْفِهِ ودِقَّتِهِ لا يَفْنَى—كما أنّ النور لا يَفْنَى؛ ولا ريب في ذلك. فإنّ النارَ حقًّا تُسْنِدُ الأنفاسَ الحيويّة (برانا)؛ فليُفْهَمْ أنّ ذلك المُسْنِدَ هو الجِيفا (jīva)، الذاتُ الحيّةُ المتجسِّدة.
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.
