श्रीभगवानुवाच The Blessed Lord said

अक्षरं ब्रह्म परमं स्वभावोऽध्यात्ममुच्यते।भूतभावोद्भवकरो विसर्गः कर्मसंज्ञितः ॥८.३॥

akṣaraṃ brahma paramaṃ svabhāvo’dhyātmamucyatebhūtabhāvodbhavakaro 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."
