Bhagavad Gita 8.5 — Remembering God at the end
अन्तकाले च मामेव स्मरन्मुक्त्वा कलेवरम्। यः प्रयाति स मद्भावं याति नास्त्यत्र संशयः ॥
antakāle ca māmeva smaranmuktvā kalevaram | yaḥ prayāti sa madbhāvaṃ yāti nāstyatra saṃśayaḥ ||
Meaning
Whoever leaves the body at the time of death remembering me alone attains my being — there is no doubt about this.
In today's life
What we remember most through life is what comes to mind at the end — so build the daily habit of remembering God.
