Once upon a time...
in a culture more wise than our own,
women were thought to possess the fingers of the gods.
They traveled to temples in the hope of being trained
as holy goddesses of love.
The ones accepted were tutored in the romantic & sensual arts.
A bright sensual imagination combined with skill
could transport the receiver to divine and electric places
within his or her soul and body.
A magical experience.
History, history, history, long and complicated.
Until somehow receiving this from a professional became a bad thing,
and the goddesses of love went underground.
And persisted in the form of mermaids and nymphs,
along with the lost but not forgotten stories of Geishas and Courtesans.
Some of them still exist today.
You just have to know where to look.
