He appeared with his leg laid bare,
Revealing himself upon his leg, exposing
And the sight of him barred the way to reason.
His state with his mirror, hindering pilgrimage

You see him, whenever he appears walking,
You see him when he starts to walk
As a pillar of light in the darkness.
The light flowing in the darkness
