Author talk:Miguel de Cervantes

Just want to know if anyone has information about a passage in which Cervantes talks about humans being thought of being parisites on a part of a larger being. For example we (humans) are like a big universe for the skin mite type parisites that feed on our bodies; and they in turn, a universe for even smaller parisites. We are also a larger universe for the various red and white blood cells and parisites within our body's interstructure. Really could use some help finding this passage. —unsigned comment by 75.41.165.186 (talk).
