Bhagavad Gita Chapter 8, Verse 4

अन्तकाले च मामेव स्मरन्मुक्त्वा कलेवरम् | य: प्रयाति स मद्भावं याति नास्त्यत्र संशय: ||

anta-kāle ca mām eva smaran muktvā kalevaram yaḥ prayāti sa mad-bhāvaṁ yāti nāsty atra saṁśayaḥ

Whoever, at the time of death, remembering Me alone, leaves the body, attains My nature. There is no doubt about this.

Krishna delivers one of the Gita's most profound teachings: 'Anta-kale cha mam eva smaran'—whoever, at the time of death (anta-kale), remembering (smaran) Me (mam) alone (eva), 'muktv kalevaram'—leaving (muktv) the body (kalevaram), 'yah prayati sa mad-bhavam yati'—he (sah) goes (prayati) and attains (yati) My nature (mad-bhavam). 'Nasty atra samshayah'—there is no doubt (samshayah) about this (atra). This is the core teaching of Chapter 8: what you remember at death determines where you go. If you remember Krishna at death, you attain Krishna's nature—liberation, union with the Supreme. This isn't about controlling death—it's about preparing during life. What you think about daily becomes your state at death. Practice remembering Krishna now, so it's natural at the final moment. The state of consciousness at death comes from daily cultivation.
