Living in the Ocean

What accounts for the thinking of people? The strange thing about trying to account for the thinking of people is that it is not something going on just in their heads. It seems to me sometimes that the mind is like a fish in water, swimming in the medium of Mind, and the thing about the medium of Mind is that it is like an ocean, subject to tides and inner currents. The deeper you can go, one would think, the more stable you can be. But there are currents in the deep, invisible and unexpected. And in the end Mind is greater than any swimming mind. People learn to swim in it, to go with it, to be carried by the tides and currents. The thing is to be aware of these invisible motions, to chart something of where they go and what they reach. I do believe people not only swim but are also are carried, and it is often this which baffles us about the confluence of ideas we see in others.
