I feel like in joyas voladoras stated multiple metaphor in the passage.

To me this mean that all things from the biggest animal to even bacteria have a life. For example in the passage he states, “Unicellular bacteria have no hearts at all; but even they have fluid eternally in motion,washing from one side of the cell to the other ,swirling and whirling.”this quote basically explains like even things with no hearts still lives in some matter ,shape, or even form. Another metaphor doyle used in his essay was “ when young we think there will come one person who will savor and sustain us always: when we are older
