Buddha argued that our external world is in perpetual, unattainable flux, and consequently, so too are we. We are but collections of constantly changing interactions between the world and our thoughts, and thus, the idea of a fixed, independent, identifiable self is a delusion. This is essential to understand because it suggests that the self that we are trying to satisfy, escape, or eternalize never even really exists in the first place. Rather, the capital I that we describe is merely a state of emptiness constantly being filled and emptied by the succession of each moment.
