Bhagavad Gita 8.23 — The two paths
यत्र काले त्वनावृत्तिमावृत्तिं चैव योगिनः। प्रयाता यान्ति तं कालं वक्ष्यामि भरतर्षभ ॥
yatra kāle tvanāvṛttimāvṛttiṃ caiva yoginaḥ | prayātā yānti taṃ kālaṃ vakṣyāmi bharatarṣabha ||
Meaning
Now I will tell you, best of the Bharatas, the times at which yogis who depart do not return, and the times at which they return.
