2.13. Just as the boyhood, youth and old age come to the embodied Soul in this body, in the same manner is the attaining of another body; the wise man is not deluded at that.
Shri Purohit Swami
2.13 As the soul experiences in this body infancy, youth and old age, so finally it passes into another. The wise have no delusion about this.
Sri Abhinav Gupta
2.12-13 Na hi etc. Dehinah etc Never indeed did I not exist, but I did exist [always]. Likewise are you and these kings. If there can be lamentability for one, on attaining change in physical form then why is one not lamented over when one attains the youth from the boyhood ? He, who is wise, does not lament. But, wisdom is easily attainable for him whose concern is not even for this [present] body. Therefore you must seek wisdom.
2.13 As the self is eternal, one does not grieve, thinking that the self is lost, when an embodied self living in a body gives up the state of childhood and attains youth and other states. Similarly, the wise men, knowing that the self is eternal, do not grieve, when the self attains a body different from the present body. Hence the selves, being eternal, are not fit objects for grief.
This much has to be done here; the eternal selves because of Their being subject ot beginningless Karma become endowed with bodies suited to Their Karmas. To get rid of this bondage (of bodies), embodied beings perform duties like war appropriate to their stations in life with the help of the same bodies in an attitude of detachment from the fruits as prescribed by the scripture. Even to such aspirants, contacts with sense-objects give pleasure and pain, arising from cold, heat and such other things. But these experiences are to be endured till the acts enjoined in the scriptures come to an end.
The Lord explains the significance immediately afterwards:
2.13 As to that, to show how the Self is eternal, the Lord cites an illustration by saying,‘৷৷.of the embodied,’ etc. Yatha, as are, the manner in which; kaumaram, boyhood; yauvanam, youth, middle age; and jara, decrepitude, advance of age; dehinah, to an embodied being, to one who possesses a body (deha), to the Self possessing a body; asmin, in this, present; dehe, body . These three states are mutually distinct. On these, when the first state gets destroyed the Self does not get destroyed; when the second state comes into being It is not born. What then? It is seen that the Self, which verily remains unchanged, acires the second and third states. Tatha, similar, indeed; is Its, the unchanging Self’s dehantarapraptih, acisition of another body, a body different from the present one. This is the meaning. Tatra, this being so; dhirah, an intelligent person; na, does not; muhyati, get deluded.
2.13 Just as the self associated with a body passes through childhood, youth and old age (pertaining to that body), so too (at death) It passes into another body. A wise man is not deluded by that.
2.13 As are boyhood, youth and decrepitude to an embodied being in this (present) body, similar is the acisition of another body. This being so, an intelligent person does not get deluded.
2.13 Just as in this body the embodied (soul) passes into childhood, youth and old age, so also does it pass into another body; the firm man does not grieve thereat.
2.13 देहिनः of the embodied (soul)? अस्मिन् in this? यथा as? देहे in body? कौमारम् childhood? यौवनम् youth? जरा old age? तथा so also? देहान्तरप्राप्तिः the attaining of another body? धीरः the firm? तत्र thereat? न not? मुह्यति grieves.Commentary – Just as there is no interruption in the passing of childhood into youth and youth into old age in this body? so also there is no interruption by death in the continuity of the ego. The Self is not dead at the termination of the stage? viz.? childhood. It is certainly not born again at the beginning of the second stage? viz.? youth. Just as the Self passes unchanged from childhood to youth and from yourth to old age? so also the Self passes unchanged from one body into,another. Therefore? the wise man is not at all distressed about it.
