Acharya Prashant explains that the ego is fundamentally a sense of incompleteness that seeks to sustain itself by dividing the infinite Truth into small, named fragments. He notes that the ego can only consume what is smaller than itself and fears the vastness of the nameless Truth, as the infinite would dissolve the ego's separate identity. Consequently, the ego creates artificial distinctions and labels, turning a singular reality into a world of diverse objects to satisfy its endless desires. He uses the example of carbon, which is the essence of both coal and diamonds, to illustrate how the ego ignores fundamental truth in favor of worldly value and status.
