The word samsara in verse 60, which refers to the cycle of birth and death, means literally “that which is moving intensely,” that is, the everyday world of incessant change. Immature people, living unreflectively from moment to moment, drown in the instability of samsara, which drags on as endlessly as night for the insomniac. That is because this kind of immaturity is not that of a child, but of the adult who is not sensitive to that moment of discrimination when one choice will lead toward wisdom and the other to bitter pain (66).
