Bhagavad Gita · Chapter 8: The Imperishable Absolute

Bhagavad Gita 8.27

naite sṛtī pārtha jānanyogī muhyati kaścana | tasmātsarveṣu kāleṣu yogayukto bhavārjuna ||

No yogi who knows these two paths is ever deluded, Arjuna. Therefore, at all times, be steadfast in yoga.

Modern context

Here Krishna draws the practical conclusion, and it is not about timing at all. Since a person knows the two paths, they are not confused, and so they should simply be steady in yoga at all times. The details of seasons and fortnights fall away. What matters is not the moment of death but the quality of every moment before it. A life lived steadily in the light leads to the light, whatever the date.
