Bhagavad Gita Chapter 18, Verse 54

ब्रह्मभूतः प्रसन्नात्मा न शोचति न काङ्क्षति | समः सर्वेषु भूतेषु मद्भक्तिं लभते पराम् ||

brahma-bhūtaḥ prasannātmā na śocati na kāṅkṣati samaḥ sarveṣu bhūteṣu mad-bhaktiṁ labhate parām

Having become Brahman, with a joyful mind, one neither grieves nor desires. Equal to all beings, one attains supreme devotion to Me.

Krishna explains the state of one who has transcended the gunas. 'Brahma-bhūtaḥ prasannātmā na śocati na kāṅkṣati'—having become Brahman (brahma-bhūtaḥ), with a joyful mind (prasannātmā), one neither grieves (na śocati) nor desires (na kāṅkṣati). 'Samaḥ sarveṣu bhūteṣu mad-bhaktiṁ labhate parām'—equal (samaḥ) to all beings (sarveṣu bhūteṣu), one attains (labhate) supreme devotion to Me (mad-bhaktiṁ parām). This is the result: when you become established in Brahman, you become joyful, free from grief and desire, equal to all beings, and you naturally attain supreme devotion to Krishna. This devotion is not separate from realization of Brahman—it's the natural outcome. When you transcend the gunas and become established in Brahman, supreme devotion arises naturally.
