Bhagavad Gita 2.13
As the soul experiences infancy, youth, and old age in this body, so finally it passes into another; the wise have no delusion about this.
देहिनोऽस्मिन्यथा देहे कौमारं यौवनं जरा।
तथा देहान्तरप्राप्तिर्धीरस्तत्र न मुह्यति॥dehino'sminyathā dehe kaumāraṃ yauvanaṃ jarā|
tathā dehāntaraprāptirdhīrastatra na muhyati||
