Bhagavad Gita 8.3
श्री भगवानुवाच · śrī bhagavānuvāca
अक्षरं ब्रह्म परमं स्वभावोऽध्यात्ममुच्यते।भूतभावोद्भवकरो विसर्गः कर्मसंज्ञितः॥
akṣaraṃ brahma paramaṃ svabhāvo'dhyātmamucyate |bhūtabhāvodbhavakaro visargaḥ karmasaṃjñitaḥ ||
The Blessed Lord said, "Brahman is the Imperishable, the Supreme; its essential nature is called Self-knowledge; the offering (to the gods) that causes the existence and manifestation of beings and sustains them is called action."
The Lord Shri Krishna replied: The Supreme Spirit is the Highest Imperishable Self, and Its nature is spiritual consciousness. The worlds have been created and are sustained by an emanation from the Spirit, which is called the Law.
Our plain-language meaning of this verse is waiting for scholar review.
