What is the difference between this?
Minerals following similar same paths appear white. Likely, the lichens are feeding on the minerals carried with the water from their own cracks.
The minerals take on crystallized form when they evaporate. The lichens, in complex crystalline forms, appear to be evaporation as well. Life, it appears, rises at intersections of different forms of energy. Is it any wonder that human thought works that way as well? What if human thought is akin to lichen? What if it is not ours but the earth’s, and we are like stones on a late winter mountainside?
