कर्म ब्रह्मोद्भवं विद्धि ब्रह्माक्षरसमुद्भवम्। तस्मात्सर्वगतं ब्रह्म नित्यं यज्ञे प्रतिष्ठितम्।।

karma brahmodbhavaṁ viddhi brahmākṣara-samudbhavam tasmāt sarva-gataṁ brahma nityaṁ yajñe pratiṣṭhitam

karma (duty) brahma (the Vedas) udbhavam (produced from) viddhi (know) brahma (the Vedas) akṣara (the Supreme/Imperishable) samudbhavam (produced from) tasmāt (therefore) sarva-gatam (all-pervading) brahma (transcendence) nityam (eternally) yajñe (in sacrifice) pratiṣṭhitam (situated)

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.

Kṛṣṇa traces the origin of duty. Prescribed activities are given in the Vedas, and the Vedas are directly manifested from the Supreme Lord. Therefore, the all-pervading Divine is eternally present in every act of sacrifice. This means that your work is not mundane; it is a direct connection to God if done correctly. When you do your duty as an offering, you are tapping into the primary energy of the universe. The workplace is as holy as the temple when the consciousness is one of sacrifice. Arjuna’s role as a warrior is not a secular job; it is a Vedic injunction. By performing it, he is participating in the divine energy. Kṛṣṇa is showing him that God is not found by avoiding work, but by performing work with the realization that the activity itself is a manifestation of the Divine.
