The Gītā assures us that the pure Being, the Self is my true nature, the real Me, is imperishable – birth-less and deathless – and just as It remains changeless through my child’s body, youthful body, and the adult body, It remains unchanging at the death of this body also.

नैनं छिन्दन्ति शस्त्राणि नैनं दहति पावकः। 
न चैनं क्लेदयन्त्यापो न शोषयति मारुतः॥ २.२३॥

शस्त्र इस शरीरी को काट नहीं सकते अग्नि इसको जला नहीं सकती जल इसको गीला नहीं कर सकता और वायु इसको सुखा नहीं सकती। (२.२३)

Weapons cleave It not, fire burns It now, water moistens It not, wind dries It not. (2.23)

The Gītā assures us that the pure Being, the Self is my true nature, the real Me, is imperishable – birth-less and deathless – and just as It remains changeless through my child’s body, youthful body, and the adult body, It remains unchanging at the death of this body also. It is deathless in all bodies. The Real never perishes. The Real ever exists. It never becomes non-existent. It cannot die on its own, nor can It be killed by another. It cannot be killed as It is the subject, and not the object. It cannot kill, or prompt any killing as It is a Witness and not the doer of action.

The Self is indestructible; It cannot be destroyed by man-made weapons, be they nuclear or human bombs, or by natural forces. The subtle or the cause cannot be destroyed by the gross or its effects. Space, which is the subtlest element, cannot be blown by air, burnt by fire, made wet by water or blasted by weapons; then how can the Self, the subtlest and the cause of all, be affected by them? Every change requires a changeless substratum. The Self is the changeless substratum for the changing body.
