All of the sense organs are both organs and capacity. The synthesizing acting of the heart continuously creates a unity of the inner world and outer world. Moments in which we perceive this unity are moments of the experience of beauty. Beauty is thus a consciousness of the heart. The heart has always been connected with love due to this relation between bringing what seems to be separated into conjoining as profound beauty.
...there are at least two ways to understand what it means to have our hearts broken. One is to imagine the heart broken into shards and scattered about—a feeling most of us know, and a fate we would like to avoid. The other is to imagine the heart broken open into new capacity—a process that is not without pain but one that many of us would welcome. As I stand in the tragic gap between reality and possibility, this small, tight fist of a thing called my heart can break open into greater capacity to hold more of my own and the world's suffering and joy, despair and hope.
