Dehino 'smin yathā dehe (BG 2.13). Dehe means in this body, and dehī means the person who is within this body, he is there, from that pealike form. Because my form, my measurement, is so small that we cannot see. It is not possible. It is ten-thousand . . . one ten-thousandth part of the tip of the hair. It is so small. So with our material eyes, or our material conception, we cannot see the soul. But the soul is there, and the proof is, evidence is, because the soul is there, therefore the pealike form, material body, is growing.
Wherever there is growth . . . there are six symptoms of presentation of . . . presence of the soul. Growth is one of the important. So growth. As soon as the soul is out of this body, no more growth. If the child comes dead, oh, there will be no growth. Oh, the parents will say: "It is useless. Throw it." So similarly, Lord Kṛṣṇa gave this first example to Arjuna that, "Don't think that the spiritual spark which is within the body, due to whose presence the body is growing from childhood to boyhood, boyhood to youthhood, from youthhood to old age . . . so therefore, when this body becomes useless, imperceptibly, the soul gives up this body." Vāsāṁsi jīrṇāni yathā vihāya (BG 2.22). Just like we give up old dress and take another, new dress, similarly, we accept another body.
