Original composition of this song was in 1988 by
Q Lazzarus and featured in the film The Silence of the Lambs
This song is a reference to the Hindu text Bhagavad Gita,
in which the five horses that pull Krishna and Pandava prince
Arjuna's chariot, are symbols of the five senses.
These five senses keep us tied to the physical/material
plane of existence. When you can transcend the limitations
of these senses and achieve a higher level of consciousness,
you are leaving the "horses" behind - "flying over them.
The song is about someone who was so affected by a loss
they decide to give up the things that keep them tied to
this world by emotion.
