Acharya Prashant explains that the common understanding of sin and virtue is often used to suppress and trap individuals. He clarifies that sin is not a moral or traditional concept but is deeply related to the state of the human ego. According to him, sin is anything that deepens the ego's ignorance and bondage, while virtue is that which leads the ego toward liberation from suffering. He emphasizes that the root of all sin is self-ignorance—not knowing who one truly is. When the ego begins to understand itself, it realizes its own non-existence, which is the essence of self-knowledge.
