Acharya Prashant explains that the soul is indestructible, unaffected by weapons, fire, water, or wind. He clarifies the concept of the cycle of eighty-four lakh births, stating that it is not merely a post-death phenomenon but a continuous process occurring in the present. Rebirth happens because our death is incomplete; we carry forward residual identifications, attachments, and past memories into the next moment. This carrying forward of the past is what constitutes the cycle of birth and death. To break this cycle, one must achieve 'complete death,' which means the total dissolution of the ego and the entire content of the mind, leaving nothing to be carried forward into time.
