Acharya Prashant explains that duality is the root of all suffering because it creates a false sense of separation between the self and the world. This separation leads to a feeling of incompleteness, making an individual a beggar who seeks fulfillment from the external world. He clarifies that the world is merely a projection of one's own consciousness, existing in three dimensions only because our physical bodies and brains are limited to that perception. Just as a mirror cannot show something that is not already present in the face, the world cannot provide anything that is not already within the individual. True fulfillment comes from going beyond the three qualities of nature—Sattva, Rajas, and Tamas—to reach a state of liberation. He further elaborates that the world is like a shadow that can neither be caught nor discarded. Suffering arises when we chase this shadow, assigning subjective meanings and values to objects based on our internal tendencies or 'vrittis'. Acharya Prashant emphasizes that Advaita is not a rigid dogma but a process of sincere inquiry into the nature of the 'seer' rather than the 'seen'. He uses the analogy of a doctor treating the eye instead of the distorted image it perceives. By questioning the source of our thoughts, likes, and dislikes, we can uncover the conditioning that drives our actions. He concludes that right action is impossible without self-knowledge; one must first understand 'who am I' before deciding 'what to do'.
