Shloka 18

चेतनेन समेतस्य पञ्चविंशतिकस्य ह । एकत्वं वै भवत्यस्य यदा बुद्धा न बुध्यते,जब जीवात्मा बुद्धिके द्वारा जडवर्गको अपना नहीं समझता अर्थात्‌ उससे सम्बन्ध नहीं जोड़ता, तब नित्य चेतन परमात्मासे संयुक्त हुए उस जीवात्माकी परमात्माके साथ एकता हो जाती है

cetanena sametasya pañcaviṁśatikasya ha | ekatvaṁ vai bhavaty asya yadā buddhā na budhyate ||

Vasiṣṭha said: When the individual self—counted among the twenty-five principles and conjoined with pure consciousness—no longer ‘knows’ through the intellect, that is, when it ceases to appropriate the inert aggregate as ‘I’ or ‘mine’, then its oneness with the Supreme, ever-conscious Reality is realized.

Educational Q&A

Liberation arises when the self stops identifying with the inert psycho-physical aggregate through buddhi; with the collapse of ‘I/mine’ appropriation, the self’s unity with the ever-conscious Supreme is realized.

In the Śānti Parva’s instruction on liberation, Vasiṣṭha explains a Sāṅkhya-leaning analysis: the self (counted among the tattvas) is associated with consciousness, and when intellect ceases to project identification, the realization of oneness with the Supreme follows.
