I will tell you, O best of the Bharatas, the time at which yogis depart and do not return, and the time at which they depart and do return.
Explanation
Krishna is answering Arjuna's question from the start of the chapter about how the self-controlled know him at death. Here he introduces the topic: there are times of departure linked with no return to rebirth (anāvṛtti) and with return (āvṛtti). The next verses describe these as two paths, and commentators differ on whether they refer to literal times of day and year or to stages or deities that guide the soul.
