Fleas interest me so much

Fleas interest me so much
that I let them bite me for hours.
They are perfect, ancient, Sanskrit, machines that admit of no appeal.
They do not bite to eat,
they bite only to jump;
they are the dancers of the celestial sphere, delicate acrobats
in the softest and most profound circus; let them gallop on my skin,
divulge their emotions,
amuse themselves with my blood,
but someone should introduce them to me. I want to know them closely,
I want to know what to rely on.

(Pablo Neruda)
