By habit we perceive ourselves and the world around us as solid, real, and enduring. Yet without much effort, we can easily determine that not one aspect within the whole world's system exists independent of change. I had just been in one physical location, and now I was in another; I had experienced different states of mind. We have all grown from babies to adults, lost loved ones, watched children grow, known changes in weather, in political regimes, in styles of music and fashion, in everything. Despite appearances, no aspect of life ever stays the same. The deconstruction of any one object—no matter how dense it appears, such as an ocean liner, our bodies, a skyscraper, or an oak tree—will reveal the appearance of solidity to be as illusory as permanence. Everything that looks substantial will break down into molecules, and into atoms, and into electrons, protons, and neutrons. And every phenomenon exists in interdependence with myriad other forms. Every identification of any one form has meaning only in relationship to another. Big only has meaning in relation to small. To mistake our habitual misperceptions for the whole of reality is what we mean by ignorance, and these delusions define the world of confusion, or samsara.
