Chapter 2 · Verse 13
Sankhya Yoga
सांख्ययोग
In plain words
You are called to remain calm and steady through all of life's transitions. Just as you naturally grow from childhood to old age without losing your inner identity, your soul simply moves to a new body at death. Realizing this truth frees you from the fear of change and ending.
Translation
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.
Meaning
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.
Word by word
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.
