Acharya Prashant clarifies a common misconception regarding the Shrimad Bhagavad Gita, stating that it does not support the idea of the soul migrating from one body to another. He explains that the term used in the relevant verses is 'Dehi' or the individual entity, not the 'Atman' or soul. The soul is birthless and deathless, and it does not enter or exit a body. He attributes the increase in human population to the play of nature, comparing it to the sudden appearance and disappearance of insects after rain. Nature expands and contracts its species based on conditions, and there is no mystical entry of a soul into a body; life begins from biological seeds like sperm and eggs when they find favorable conditions.
