कर्म ब्रह्मोद्भवं विद्धि ब्रह्माक्षरसमुद्भवम्। तस्मात्सर्वगतं ब्रह्म नित्यं यज्ञे प्रतिष्ठितम्॥
karma brahmodbhavam viddhi brahmakshara-samudbhavam tasmat sarva-gatam brahma nityam yajne pratishthitam
Translation
Know that action arises from the Vedas, and the Vedas arise from the Imperishable. Therefore, the all-pervading Brahman is eternally established in sacrifice.
Commentary
The entire chain of creation traces back to the Imperishable Brahman. Since Brahman is established in sacrifice, performing selfless action connects one directly to the ultimate reality.
