Krishna introduces the final, highly mystical topic of the chapter: the mechanics of the soul's departure. He says: But now (tu), O best of the Bharatas (bharatarṣabha), I shall speak of and explain to you (vakṣyāmi) that specific time and condition (taṃ kālaṃ) departing at which (yatra kāle prayātā), the Yogis (yoginaḥ) attain the state of non-return/liberation (anāvṛttim yānti), and conversely, the time departing at which they attain the state of return/reincarnation (āvṛttiṃ caiva).
