Text

According to Vedic opinion, there are two ways of passing from this world – one in light and one in darkness. When one passes in light, he does not come back; but when one passes in darkness, he returns.

Purport

The same description of departure and return is quoted by Ācārya Baladeva Vidyābhūṣaṇa from the Chāndogya Upaniṣad (5.10.3–5). Those who are fruitive laborers and philosophical speculators from time immemorial are constantly going and coming. Actually they do not attain ultimate salvation, for they do not surrender to Kṛṣṇa.
