Acharya Prashant explains that the doer is defined by the tendency to accumulate and expand the self. In contrast, paying the price involves disaccumulation, reduction, and the dissolution of what one is attached to or proud of. He asserts that when one acts as the doer, they are incapable of paying the price because their actions are always geared toward gathering rather than giving away. He emphasizes that confusion is often necessary because it disrupts the self-assured certainty that people use to justify their actions. He points out that most people lack confusion because they are both the doer and the judge of their own deeds, leading to biased self-validation. He uses the analogy of a car manufacturer creating both the product and the mind that values it to show how external influences shape our benchmarks for success. Regarding the concept of sureness, Acharya Prashant clarifies that it is not a mental state or something that can be imposed upon oneself through willpower or motivation. Instead, sureness is the absence of contradiction, conflict, and mental blinders. It is a state of seeing things so clearly and directly that they can no longer be denied. He explains that sureness is a totality; one cannot be selectively sure. When the mind is clear, it is sure of everything simultaneously rather than focusing on a single point. True sureness is not an affirmative statement but a natural result of the absence of internal division.
