Acharya Prashant explains that science is the method for resolving doubts concerning the material world and physical objects. By observing, testing, and experimenting, one can establish facts about the physical reality. However, even when all physical curiosities are satisfied, a deeper, causeless doubt often remains within the human mind. This internal restlessness manifests as a feeling that something is incomplete or wrong, even when one cannot pinpoint the exact cause. This fundamental doubt is the root of all other superficial doubts and persists regardless of scientific progress. He identifies this causeless doubt as 'Maya' or the 'ego' (Aham). While Truth is eternal and infinite, Maya is eternal but finite, meaning it can be ended. The ego is the first manifestation that arises from the soul, leading to the creation of the entire world of perceptions. The ego suffers from a lack of self-trust, which compels it to seek security and reliability in external things and people. Acharya Prashant suggests that instead of trying to secure or save this fragile ego, one should accept its inherent hollowness and instability. By acknowledging that the 'self' we identify with is transient and unreliable, we move beyond the need for constant self-protection. Using the metaphor of a broken-down car, he describes the human condition of trying to navigate life with faulty internal tools. We often blame external circumstances like the road or traffic for our suffering, but the real issue lies in our own 'vehicle'—the body and mind. True self-observation involves realizing that this vehicle is incapable of completing the journey. Once a person steps out of this 'broken car' of the ego, they are liberated from the cycle of deception and misplaced trust. He concludes that spiritual progress begins when one stops trusting their own confused internal mechanisms and looks inward to address the root cause of their restlessness.
