Acharya Prashant explains that the nature of the world is constant change, much like a flowing river. He references the Greek philosopher Heraclitus, who stated that one can never step into the same river twice, to emphasize that nothing in the world is stable or constant. Time itself is described as the rate of change measured by the mind. Because the world is in a state of flux, thoughts—which are merely influences from the external world—are also constantly changing. He argues that no thought or desire is truly original or internal; they are all internalized influences from one's environment, such as the desire to become a policeman or an engineer based on societal trends or media. He describes the human condition as often helpless because individuals do not know what they will want next, as their desires depend on the random flow of worldly influences. To live intelligently, one must maintain a center or core that remains untouched by this flow. While thoughts arise from the world, the capacity to realize and understand stands apart from it. Acharya Prashant uses the analogy of standing on a riverbank: one can watch the water flow without being carried away by it. He advises living in the world without being corrupted by it, illustrating this with the advice to 'cross the river but don't wet your feet.' Finally, he distinguishes between living by thought and living in realization. Thinking is rooted in the past and the external world, leading to suffering, tension, and insecurity. Realization, however, comes from deep attention to the present and is the end of suffering. He concludes that by paying attention and seeing the world for what it is, one becomes free from its happenings. This freedom allows for independent action and true joy, enabling an individual to live in the world without being ruled by its changing ideologies or market temptations.
