Acharya Prashant explains that sin is not an action one commits, but rather the very existence of a separate 'I' identity. He clarifies that the biblical statement 'all have sinned' refers to the fact that the moment an individual identifies as a separate entity from God, they have entered into sin. This 'I' represents the birth of duality, where one believes in multiple realities—the self, the world, and God—instead of the singular, absolute truth. Therefore, as long as one maintains a personal identity, it is impossible not to be a sinner. The speaker critiques the traditional religious concept of repentance, arguing that it often becomes a standalone virtue rooted in guilt. He asserts that feeling guilty or repenting as a separate individual only reinforces the sin by maintaining the 'I' that is separate from God. True repentance is not about feeling bad or small; it is the dissolution of the individual identity itself. He suggests that moving from one identity to another, even a 'pious' one, does not solve the problem because any identity apart from the one truth is a fragment and thus a sin. To be absolved of sin, Acharya Prashant advocates for living in the 'God identity,' which he equates to having no identity at all. He references the Upanishadic mahavakya 'Aham Brahmasmi' (I am Brahman) as the heart of spirituality, explaining that it is a statement of ultimate humility rather than ego. By declaring 'I am God,' one is actually saying 'I am nothing' or 'I am nobody,' thereby rejecting all petty, limited, and fragmented identities. He concludes that the only real repentance is the clearing away of the 'I' belief, as suffering and sorrow only exist when one is attached to a limited sense of being.
