Acharya Prashant addresses the question of the limit of forgiveness by explaining that the need to forgive only arises when one is hurt. He suggests that the ideal state is to be strong enough to not get hurt in the first place. True forgiveness is marked by the complete absence of hurt; if one still feels hurt or desires revenge, they have not truly forgiven. He emphasizes that while forgiveness is considered a virtue, it is even greater to be free from the need to forgive by becoming invulnerable to emotional injury. He uses the metaphor of the sky to describe this inner strength, noting that unlike steel, which can be cut or melted, the sky is 'nothing' and therefore cannot be harmed or disturbed by external forces.
