Acharya Prashant explains that the soul is non-dual and does not undergo any journey, as there is no second entity to interact with it. He critiques the common misconception of the soul's journey, noting that travel implies a limited object moving at a finite speed within the world, whereas the soul is beyond all laws and limitations. He asserts that the question of what happens to an individual after death is nonsensical because the identity one currently holds is entirely perishable. Since people identify only with that which is subject to death, nothing of that identity remains after the body is destroyed. He emphasizes that the physical body and the mental constructs associated with it will turn to ash and cease to exist. The speaker warns against the delusion that some part of the personal 'I' survives death, stating that such beliefs only serve to encourage a life based on wrong relationships and attachments. He clarifies that the soul is not a material object, wave, or entity residing inside the body that exits upon death. When an individual dies, their perception of the world and time also ends, making terms like 'after' or 'future' meaningless. He concludes by stressing the importance of self-knowledge, as without it, one remains trapped in worldly entanglements and baseless theories.
