Dust Particles In A Shaft Of Light
A beam of sunlight filters in through an open window of a room bathed in shadow. The air is still. In the ray of light, dust particles bounce off of one another, illuminated. The fine concentration of light is filled with tiny, radiant specs that are suspended in space, and yet, in motion: floating, shimmering, tumbling together, touching, separating, touching once more.
The physics of it does not matter. The dust-air interaction does not matter. Brownian motion does not matter. Lucretius’ remarkable vision poem of atoms randomly moving in an infinite universe does not matter. Nor does Einstein’s explanation of it. Here’s what matters: You can see it. It is the dust of the world, dazzling in the light.
This is your whole life, right here, right now, contained and elevated, in the ephemeral ray of light pouring in. And you tell yourself: this is the dust of me, the dust around me, what I breathe in, what I breathe out. The dust is filled with thoughts, memories. Mine, yours. Dust from old books. Dust of letters I’ve opened, of papers torn. Dust from my son’s drawings. Dust from cars as their tires leave behind bits of journeys that float through my window, into the beam. Dust of a tissue from my mother’s purse. Dust of my cats, here, and then not here, alive in an eternal way, I suppose, luminous in this narrow beam. Tears evaporate and find their way into the shining zig zag motion. Cherish what you have, and what you have lost. Look for it all, shimmering and tumbling, as dust particles in a shaft of light.
