11.22.49

आत्मन: पितृपुत्राभ्यामनुमेयौ भवाप्ययौ । न भवाप्ययवस्तूनामभिज्ञो द्वयलक्षण: ॥ ४९ ॥

ātmanaḥ pitṛ-putrābhyām anumeyau bhavāpyayau na bhavāpyaya-vastūnām abhijño dvaya-lakṣaṇaḥ

ātmanaḥ
one’s own
pitṛ
from the father or ancestors
putrābhyām
and the son
anumeyau
can be surmised
bhava
birth
apyayau
and death
na
is no longer
bhava-apyaya-vastūnām
of all that is subject to generation and destruction
abhijñaḥ
one who is in proper knowledge
dvaya
by these dualities
lakṣaṇaḥ
characterized

By the death of one’s father or grandfather one can surmise one’s own death, and by the birth of one’s son one can understand the condition of one’s own birth. A person who thus realistically understands the creation and destruction of material bodies is no longer subject to these dualities.
