Sanskrit
कर्म ब्रह्मोद्भवं विद्धि ब्रह्माक्षरसमुद्भवम् । तस्मात्सर्वगतं ब्रह्म नित्यं यज्ञे प्रतिष्ठितम् ॥
karma brahmodbhavaṃ viddhi brahmākṣarasamudbhavam tasmāt sarvagataṃ brahma nityaṃ yajñe pratiṣṭhitam
Translation
Know thou that from Brahma action groweth, and Brahma from the Imperishable cometh. Therefore the Eternal, the all-permeating, is ever present in sacrifice.
Annie Besant · The Bhagavad-Gita, translated by Annie Besant (4th ed., 1922) — Wikisource · Public Domain
Explanation
Verse 14’s chain gets its metaphysical anchor: action traces back to Brahman, and Brahman to the Imperishable (akṣara) — so the all-pervading Eternal is, by this logic, literally present within every act of sacrifice. This is the highest point the cosmological argument reaches before verse 16 turns it back into ethical language with the wheel metaphor.
