Bhagavad Gita Chapter 3.15
karma brahmodbhavaḿ viddhi
brahmākṣara-samudbhavam
tasmāt sarva-gataḿ brahma
nityaḿ yajñe pratiṣṭhitam
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.
