Up the coast a few miles north, in a lava reef under the cliffs, there are a lot of rock pools. You can visit them when the tide is out. Each pool is separate and different, and you can, if you are fanciful, give them names – such as George, Charlotte, Kenny, Mrs Strunk. Just as George and the others are thought of, for convenience, as individual entities, so you may think of a rock pool as an entity; though, of course, it is not. The waters of its consciousness – so to speak – are swarming with hunted anxieties, grim-jawed greeds, dartingly vivid intuitions, old crusty-shelled rock-gripping obstinacies, deep-down sparkling undiscovered secrets, ominous protean organisms motioning mysteriously, perhaps warningly, toward the surface light. How can such a variety of creatures coexist at all? Because they have to. The rocks of the pool hold their world together. And, throughout the day of the ebb tide, they know no other.
But that long day ends at last; yields to the night-time of the flood. And, just as the waters of the ocean come flooding, darkening over the pools, so over George and the others in sleep come the waters of that other ocean; that consciousness which is no one in particular but which contains everyone and everything, past, present and future, and extends unbroken beyond the uttermost stars. We may surely suppose that, in the darkness of the full flood, some of these creatures are lifted from their pools to drift far out over the deep waters. But do they ever bring back, when the daytime of the ebb returns, any kind of catch with them? Can they tell us, in any manner, about their journey? Is there, indeed, anything for them to tell – except that the waters of the ocean are not really other than the waters of the pool?
