What is true of the breath is also true throughout our lives: our everyday experience isn’t one of sensations so much as of mental constructs built on top of those sensations. The simplest mental constructs are the sense-percepts themselves. These in turn are used to build increasingly complex conceptual formations. This process has been unfolding since you were born. Your mind has accumulated a huge mass of increasingly elaborate conceptual formations in an attempt to organize and simplify the enormous variety of sensory experiences you’ve been exposed to.
