Bhagwad Gita
Chapter 3, Verse 15
कर्म ब्रह्मोद्भवं विद्धि ब्रह्माक्षरसमुद्भवम्।
तस्मात्सर्वगतं ब्रह्म नित्यं यज्ञे प्रतिष्ठितम्।।3.15।।
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.
