देहिनोऽस्मिन्यथा देहे कौमारं यौवनं जरा। तथा देहान्तरप्राप्तिर्धीरस्तत्र न मुह्यति।।2.13।।
dehino ’smin yathā dehe kaumāraṁ yauvanaṁ jarā tathā dehāntara-prāptir dhīras tatra na muhyati
Just as the embodied soul passes through childhood, youth, and old age in this body, so too does it pass into another body; the steadfast one does not grieve over this.
