An analogy aims to explain an unknown idea or thing, comparing it with something that is familiar to you. Oh my soul, where are you,
Surrounded, separated, in immeasurable oceans of space,
Ceaselessly meditating, venturing, throwing, searching for the spheres to connect them,
Until the bridge that you will need to be formed, until the ductile anchor remains ,
Until the gauze string that you throw somewhere, oh my soul. ”
