योगवासिष्ठः yogavāsiṣṭhaḥ - book-6, chapter-55, verse-15

आत्मा चैकोऽस्ति न द्वित्वमसतः संभवः कुतः ।
अविनाशस्त्वनन्तोऽसौ सतो नाशो न विद्यते ॥ १५ ॥

ātmā caiko'sti na dvitvamasataḥ saṃbhavaḥ kutaḥ ,
avināśastvananto'sau sato nāśo na vidyate 15

15. ātmā ca ekaḥ asti na dvitvam asataḥ saṃbhavaḥ kutaḥ
| avināśaḥ tu anantaḥ asau sataḥ nāśaḥ na vidyate ||

15. ātmā ca ekaḥ asti dvitvam na asataḥ saṃbhavaḥ kutaḥ
asau tu avināśaḥ anantaḥ sataḥ nāśaḥ na vidyate

15. The self (ātman) is one, and there is no duality. How can the non-existent ever come into being? That self (ātman) is indeed imperishable (avināśa) and infinite (ananta); the destruction of the existent (sat) is never found.
