libro, libra, libre

Libro
{Spanish for book}
As in letter and spaces
strung together
to slip a story
under your skin.

Libra

{Spanish for pound}

As in unit of weight

measurement of mass
in the nonmetric system

Not that I own a scale

Or want to step on one

Also my zodiac rising sign

The symbol of balance 

Libre
{Spanish for free}
As in liberated
from a story struggling to be sung
for untold eons
