Bhagavad Gita Verses on the Soul & Immortality

देहिनोऽस्मिन्यथा देहे कौमारं यौवनं जरा। तथा देहान्तरप्राप्तिर्धीरस्तत्र न मुह्यति॥

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.

न जायते म्रियते वा कदाचि न्नायं भूत्वा भविता वा न भूयः। अजो नित्यः शाश्वतोऽयं पुराणो न हन्यते हन्यमाने शरीरे॥

It is not born, nor does it ever die; after having been, it again does not cease to be; unborn, eternal, changeless, and ancient, it is not killed when the body is killed.

वासांसि जीर्णानि यथा विहाय नवानि गृह्णाति नरोऽपराणि। तथा शरीराणि विहाय जीर्णा न्यन्यानि संयाति नवानि देही॥

Just as a man casts off worn-out clothes and puts on new ones, so too the embodied Self casts off worn-out bodies and enters others that are new.

नैनं छिन्दन्ति शस्त्राणि नैनं दहति पावकः। न चैनं क्लेदयन्त्यापो न शोषयति मारुतः॥

Weapons cannot cut it, fire cannot burn it, water cannot wet it, wind cannot dry it.

अच्छेद्योऽयमदाह्योऽयमक्लेद्योऽशोष्य एव च। नित्यः सर्वगतः स्थाणुरचलोऽयं सनातनः॥

This Self cannot be cut, burned, wetted, nor dried up; it is eternal, all-pervasive, stable, immovable, and ancient.

जातस्य हि ध्रुवो मृत्युर्ध्रुवं जन्म मृतस्य च। तस्मादपरिहार्येऽर्थे न त्वं शोचितुमर्हसि॥

For the born, death is certain, and for the dead, birth is certain; therefore, you should not grieve over the inevitable.
