Acharya Prashant explains that as long as an individual identifies with the body, they will remain trapped in duality and miss the ultimate truth. He describes the body as a 'lousy carcass' and asserts that when one perceives themselves as material, the entire world appears only as material. This body-identification creates a sense of 'others' and leads to the separate questions of 'Who am I?' and 'Who are you?'. He compares this to an unsolved mathematical equation where the two sides must be brought together to reach zero, representing the dissolution of duality. He further clarifies that searching for the ultimate reality or God in the external world—whether through money, relationships, or even visiting holy places like the Ganga—is futile if one remains body-identified. If the seeker is material, then everything they find, including a Guru or a sacred river, will be perceived only as material. He emphasizes that the ultimate joy cannot be found in possessions or designations because they exist on the same material plane as the body. The realization that 'You are me and I am you' only occurs when the individual's ego and body-identification disappear.
