Śaṅkarācārya's commentary

For that which has come into being, destruction is certain; and for that which has perished, re-birth is certain. Wherefore, regarding an unavoidable thing, thou oughtst not to grieve. The course of beings is necessary; lamentation does not alter it, and one should not lament what cannot be helped.
