Acharya Prashant explains that the feeling of dissatisfaction or unfulfillment arises primarily from a lack of honest self-inquiry. He asserts that the moment an individual honestly acknowledges their state of unfulfillment and asks where it comes from, they immediately distance themselves from that state. By becoming an observer of their own dissatisfaction, the person is no longer consumed by it. He emphasizes that unfulfillment and falsehood persist only as long as they are not questioned; they are like illusions that vanish when confronted with rigorous inquiry.
