ओमित्येकाक्षरं ब्रह्म व्याहरन्मामनुस्मरन्। यः प्रयाति त्यजन्देहं स याति परमां गतिम् ॥

oṁ ityekākṣharaṁ brahma vyāharan mām anusmaran yaḥ prayāti tyajan dehaṁ sa yāti paramāṁ gatim

"Aum!" the one syllabled Eternal, reciting, thinking upon Me, he who goeth forth, abandoning the body, he goeth on the highest path.

In plain words: Whoever leaves the body while saying "Om," the one sacred syllable that stands for the Eternal, and while thinking of Krishna, goes on the highest path.
