Acharya Prashant explains that all human conflicts and problems arise from the brain, which operates within the framework of time and space. He asserts that the future is merely an act of imagination and a recycling of past memories, as one cannot imagine something they have not experienced. The brain functions in duality, where opposites like past and future, hope and fear, and success and failure are interdependent and cannot exist without each other. This evolutionary mechanism is designed for survival, much like a rabbit's long ears, but it keeps the mind trapped in a dead past or an unborn future.
