Bhagavad Gita 13.12

ज्ञेयं यत्तत्प्रवक्ष्यामि यज्ज्ञात्वाऽमृतमश्नुते।अनादिमत्परं ब्रह्म न सत्तन्नासदुच्यते॥

jñeyaṃ yattatpravakṣyāmi yajjñātvā'mṛtamaśnute |anādimatparaṃ brahma na sattannāsaducyate ||

I will declare that which is to be known, knowing which one attains immortality; the beginningless Supreme Brahman, which is neither being nor non-being.

I will now speak to you of that great truth which one ought to know, since by it one will attain immortal bliss—that which is without beginning, the eternal spirit which dwells in me, neither with form nor without it.

Our plain-language meaning of this verse is waiting for scholar review.
