When a wave of ocean tumbles onto the shore, the white, salty froth disperses into thousands of little foam islands of all different shapes and sizes. But as the water recedes back into itself, each individual is collected back into the frothy fold. They never really left each other, but I bet they thought they did. The spaces between them after such togetherness must have felt like emptiness for sure, when all along, they were swimming in their own source.
To me, even more interesting is the rim of foam that edges the sea as it rolls out upon the beach. Though this rolls on further away from the rest, it stays connected, each bubble one with the others besides it, as if holding hands to create an invisible barrier to send all the rest back home. Not to create separation, water from land and vice versa; merely to remind them where they come from. It remains behind in absolute surrender, embracing the sand with absolute acceptance until they melt into one. And they are, after all. Are they not? Millions of years of embracing like that is how the sand came to be. The whole planet, born out of a love so big that a single grain of sand, a tiny island of substance, could not possibly know.
