Arjuna asks seven questions, and the last is the hardest: how is God known at the hour of death? Whatever you remember at the end, Krishna says, is where you go, so remember him always. He describes the imperishable, the day and night of Brahma in which worlds appear and dissolve, and the two paths of light and smoke.
Arjuna asks: what is Brahman, the Self within, action, the realm of beings, the realm of the gods, the lord of sacrifice, and how are you known at death? Krishna answers each in a line: the imperishable is Brahman, and he himself is the lord of sacrifice in this body.
adhiyajñaḥ kathaṃ ko'tra dehe'sminmadhusūdana prayāṇakāle ca kathaṃ jñeyo'si niyatātmabhiḥ
Who is the lord of sacrifice here in this body, and how, Madhusudana? And how are you to be known at the hour of death by those who are self-controlled?
The imperishable is the supreme Brahman; its own nature is called the Self within; the creative force that brings beings into existence is called action.
adhibhūtaṃ kṣaro bhāvaḥ puruṣaścādhidaivatam adhiyajño'hamevātra dehe dehabhṛtāṃ vara
The realm of beings is the perishable; the realm of the gods is the cosmic Person; and I myself, here in the body, am the lord of sacrifice, best of the embodied.
Verses 8.5–8.8
Whatever you remember at the end
Whatever state one remembers when leaving the body, to that one goes (8.6), because it is what one has been absorbed in all along. So remember me at all times, Krishna says, and fight.
With a mind disciplined by practice, not wandering elsewhere, constantly meditating, one reaches the supreme divine Person, Partha.
Verses 8.9–8.14
Smaller than the atom, bright as the sun
Meditate on the one who is smaller than the atom, the sustainer of all, coloured like the sun, beyond all darkness (8.9). Closing the gates, the breath gathered at the crown, uttering Om, one reaches the highest. For one who remembers always, he is easy to reach.
One should meditate on the Seer, the ancient, the ruler, smaller than the atom, the sustainer of all, of unthinkable form, radiant like the sun, beyond all darkness;
at the time of departure, with an unmoving mind, joined in devotion and by the strength of yoga, drawing the life-breath fully between the brows, one reaches that supreme divine Person.
What the knowers of the Veda call the imperishable, what ascetics free from passion enter, what people keep celibacy to reach: that state I will describe to you briefly.
For one who remembers me constantly, every day, with mind never turned elsewhere, I am easy to reach, Partha, for that ever-disciplined yogi.
Verses 8.15–8.22
A thousand ages, then night
A day of Brahma lasts a thousand ages, and so does his night. At dawn all beings emerge from the unmanifest; at nightfall they dissolve again, over and over (8.17–19). Beyond even that is an unmanifest that never perishes.
bhūtagrāmaḥ sa evāyaṃ bhūtvā bhūtvā pralīyate rātryāgame'vaśaḥ pārtha prabhavatyaharāgame
This same multitude of beings, coming into being again and again, dissolves helplessly at the coming of night, Partha, and emerges again at the coming of day.
That supreme Person, Partha, in whom all beings dwell and by whom all this is pervaded, is reached by undivided devotion.
Verses 8.23–8.28
The bright path and the dark
There are two paths of departure: fire, light, day and the northern sun, which do not return; smoke, night and the moon, which return (8.24–26). The yogi who knows both is never confused, and goes beyond even the merit of the Vedas.
These two paths, the bright and the dark, are thought to be eternal for the world. By one, one goes and does not return; by the other, one returns again.
Whatever merit is said to come from the Vedas, from sacrifices, austerities and gifts, the yogi who knows this goes beyond it all and reaches the supreme, primal abode.
