Tao may be known as directly as water is knowable to a fish. My Tao will not be the same as your Tao. We are both individuals, with different background and thoughts. As soon as Tao enters into us, it takes on the colors of our inner personalities. When it passes out of us, it takes on the colors of our inner personalities. This is an ongoing and constant process, like water lowing through a fish's gills. Just as the water nurtures the fish, so too does Tao nurture and sustain us. As long as we continue our immersion in Tao, we will be as safe as a carp in water. When we separate from Tao, we are as helpless as a fish out of water.
