Acharya Prashant clarifies that the immortality of the soul, as described in the Shrimad Bhagavad Gita, is only relevant to those who live as the soul. He points out the contradiction in people identifying as a 'living being' (Jiva) while reciting verses about the soul's immortality. While the soul is indestructible and unaffected by fire or weapons, the common person experiences suffering, fear, and mental agitation daily. Therefore, the Gita's teaching is a call to change how one lives, rather than a passive assurance of safety.
