I have hidden  myself
  beneath a mask: 

  With courage
  conquering fear
  shall ye
  approach me: 

  But the first 
  kiss of love shall be 
  radiant on your lips; 
 
 
 

 
   I am a black and 
  terrible God. 

  ye shall lay down 
  your heads upon 
  mine altar, expecting 
  the sweep of the sword. 

  and all my darkness
  and terror shall turn
  to light and joy.
