Having established the physical and mental lock in Verse 12, Krishna now reveals the ultimate sonic passcode for the soul's launch. He states: While situated in that state, one must vibrate and utter the sacred syllable 'OM', which is the single-syllable, imperishable representation of Brahman (oṃ ity ekākṣaraṃ brahma vyāharan). Simultaneously, one must constantly remember and fix their consciousness exclusively on Me (mām anusmaran). Whoever departs and quits their physical body in this exact manner (yaḥ prayāti tyajan dehaṃ), that person absolutely attains the supreme, ultimate destination (sa yāti paramāṃ gatim).
