देहिनोऽस्मिन्यथा देहे कौमारं यौवनं जरा।
तथा देहान्तरप्राप्तिर्धीरस्तत्र न मुह्यति।।2.13।।
।।2.13।।देहधारीके इस मनुष्यशरीरमें जैसे बालकपन जवानी और वृद्धावस्था होती है ऐसे ही देहान्तरकी प्राप्ति होती है। उस विषयमें धीर मनुष्य मोहित नहीं होता।
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 Selfs 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.
2.12-13 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:
Dehino’smin yathaa dehe kaumaaram yauvanam jaraa; Tathaa dehaantara praaptir dheeras tatra na muhyati.
dehinaḥ—of the embodied; asmin—in this; yathā—as; dehe—in the body; kaumāram—childhood; yauvanam—youth; jarā—old age; tathā—similarly; deha-antara—another body; prāptiḥ—achieves; dhīraḥ—the wise; tatra—thereupon; na muhyati—are not deluded
