As the embodied one passes in this body through childhood, youth, and old age, so does he obtain another body. The firm-minded one is not deluded in this

The fundamental analogy: dehin (the one who possesses a body, the animating principle) remains while deha (body) changes. The three stages — kaumāra (childhood), yauvana (youth), jarā (old age) — are inevitable and natural.

Dehāntara-prāptiḥ (obtaining of another body) follows the same logic. If we accept change within one life, why not between lives? The continuity is the same in both cases.

Dhīraḥ (the firm, the stable-minded) na muhyati (is not deluded/confused). Wisdom is stability in the face of change. One who understands this continuity does not grieve at death.
