Acharya Prashant explains that the sense of 'I' (the ego) is the greatest superstition because people live their entire lives centered around it without ever having seen or experienced it. He argues that this 'I' is merely a collection of things gathered from the world—physical traits, names, thoughts, and possessions—much like a product formed from a supermarket. Because the ego is constructed entirely from the material world, it is inherently incomplete and seeks fulfillment in the same world that created its sense of lack. This cycle of seeking solutions in the 'world-mall' for problems created by the world is futile and illogical.
