Air moves in rivers. Infiltrates mountainous trees, filtrates them. Fountainous trees, vibrates them. Air has been going on for a long time. Before we invented April. Or outer space. Air is accessible to our understanding. Every breath assists our thought, self-evidently. What we see is what we get, thanks to air. And that goes for all of us. Air puts down roots into every emptiness. Air is out and in, out and in, unlike the platitudes of science. Like birds, we should laugh at our fixation on measures. Air makes a clean dive and a firm back. Air variously exalts.
