Sanskrit
नान्यं गुणेभ्यः कर्तारं यदा द्रष्टाऽनुपश्यति । गुणेभ्यश्च परं वेत्ति मद्भावं सोऽधिगच्छति ॥
nānyaṃ guṇebhyaḥ kartāraṃ yadā draṣṭā'nupaśyati guṇebhyaś ca paraṃ vetti madbhāvaṃ so'dhigacchati
Translation
When the Seer perceiveth no agent other than the qualities, and knoweth That which is higher than the qualities, he entereth into My Nature.

Explanation
The philosophical center of the chapter. The escape from eighteen verses of guna-bondage isn’t picking the “best” guna — it’s the Seer (draṣṭṛ) recognizing that everything described so far, sattva’s luminosity included, was activity belonging to the gunas alone, never to the self. This is a direct continuation of chapter 13’s field/knower-of-the-field distinction: the gunas are part of the field (kshetra), and liberation is simply the knower (kshetrajna) no longer mistaking the field’s activity for its own agency. Verse 20 names the result plainly.
