A tree is an aerial garden, a botanical migration from the sea, from those earliest plants, the seaweeds; it is a purchase on crumbled rock, on ground. The human, standing, is only a different upsweep and articulation of cells. How treelike we are, how human the tree.

A black-crowned night heron stood on an apron of wet sand, looking across the channel. The feather plume at the back of his head lifted in a faint breeze. Out there the channel churned its cyclonic eddies counterclockwise. Schools of anchovies, halibut, and sea bass came and went: silver flashes, small storms that well up from the inside of the sea but are short-lived, like lightning.

Walking is also an ambulation of mind.

Everything in nature invites us constantly to be what we are.

All that's known is this: there is no central processor, no single computer. Nothing that simple. Millions of neurons process information simultaneously and in parallel, not linearly, but the actual chemistry and electrical properties of that integrative process are still being mapped. Even so, it seems odd that during the evolution of brain circuitry and thinking, the ability to understand itself did not get wired in. Such built-in innocence seems like a terrible oversight.

Perhaps despair is the only human sin.

There was not one cause for our internment, but many - a deep-seated racial prejudice working on top of fear, distrust, and greed. So how is one to say exactly where history begins or ends? It is all slow oscillations, curves, and waves which take so long to reveal themselves ... like watching a tree grow.
