Acharya Prashant explains that the soul is essential for life because, without it, a person remains trapped in nature and experiences constant suffering. He distinguishes between two types of people in the spiritual world: those who believe in a personal God and those who move toward the soul. He clarifies that sin and merit are not fundamental experiences but are social constructs and definitions that change with time and place. A child does not inherently know what sin is until taught, but the experience of bondage is immediate and universal. Therefore, he defines sin as that which increases bondage and merit as that which cuts through it. Bondage is synonymous with suffering and restlessness, and it is the only true starting point for spiritual understanding.
