Chapter 2: Sloka 13

2.13

dehino ’smin yathā dehe
kaumāraṁ yauvanaṁ jarā
tathā dehāntara-prāptir
dhīras tatra na muhyati

dehinaḥ—of the embodied; asmin—in this; yathā—as; dehe—in the body; kaumāram—boyhood; yauvanam—youth; jarā—old age; tathā—similarly; dehāntara—transference of the body; prāptiḥ—achievement; dhīraḥ—the sober; tatra—thereupon; na—never; muhyati—deluded.

As the embodied soul continually passes, in this body, from boyhood to youth to old age, the soul similarly passes into another body at death. The self-realized soul is not bewildered by such a change.
