You must try, the voice said, to become colder. I understood at once. It's like the bodies of gods: cast in bronze, braced in stone. Only something heartless could bear the full weight.

Poems offer us counter-knowledges. They let us see what is invisible to ordinary looking, and to find in overlooked corners the opulence of our actual lives. Similarly, we usually spend our waking hours trying to be sure of things - of our decisions, our ideas, our choices. We so want to be right. But we walk by right foot and left foot.

Art keeps its newness because it's at once unforgettable and impossible to remember entirely. Art is too volatile, multiple and evaporative to hold on to. It's more chemical reaction, one you have to re-create each time, than a substance. Art's discoveries are also, almost always, counter to ordinary truths.

The secret of understanding poetry is to hear poetry's words as what they are: the full self's most intimate speech, half waking, half dream. You listen to a poem as you might listen to someone you love who tells you their truest day. Their words might weep, joke, whirl, leap. What's unspoken in the words will still be heard. It's also the way we listen to music: You don't look for extractable meaning, but to be moved.

Hyesims poems: transformative as walking high granite mountains by moonlight, with fragrant herbs underfoot and a thermos of clear tea in the backpack. Their bedrock is thusness, their images beauty is pellucid and new, their view without limit. The shelf of essential Zen poets for American readers grows larger with this immediately indispensable collection.

A poem makes clear without making simple. Poetry's language carries what lives outside language. It's as if you were given a 5-gallon bucket with 10 gallons of water in it. Mysterious thirsts are answered. That alchemical bucket carries secrets also, even the ones we keep from ourselves.

A poem can use anything to talk about anything.
