Bhagavad Gita
3.15

कर्म ब्रह्मोद्भवं विद्धि ब्रह्माक्षरसमुद्भवम् | तस्मात्सर्वगतं ब्रह्म नित्यं यज्ञे प्रतिष्ठितम् ||१५||

karma brahmodbhavaṁ viddhi brahmākṣhara-samudbhavam tasmāt sarva-gataṁ brahma nityaṁ yajñe pratiṣhṭhitam

Translation

Regulated activities are prescribed in the Vedas, and the Vedas are directly manifested from the Supreme Personality of Godhead. Consequently the all-pervading Transcendence is eternally situated in acts of sacrifice.

Interpretation

The cosmic chain continues upward: karma → Brahman (the Vedas/cosmic principle) → Akshara Brahman (the eternal, unchanging divine source). All action is ultimately grounded in the divine. Yajna (sacrifice) is not a human invention but the expression of a cosmic law already embedded in the structure of existence.
