"Connections are made slowly; sometimes they grow underground," writes Marge Piercy in her book Circles in the Water. "You cannot tell always by looking what is happening. More than half a tree is spread out in the soil under your feet." Piercy advises us to use this strategy in our own lives. "Penetrate quietly as the earthworm. Spread like the squash plant that overruns the garden. Gnaw in the dark and use the sun to make sugar. Keep tangling and interweaving and taking more in, a thicket and bramble wilderness to the outside, but to us interconnected with burrows and lairs."
