English Translation (by Deborah Goldsmith and Ryoko Toyama)
The trembling string of a taut bow
Your Heart is unsettled by the Moonlight
The beauty of a sharp blade
Thy profile, very much like its edge
Thy [bad word] heart hides behind the sorrow and anger
The spirits of the forest know it
Only the Mononoke
Only the Mononoke

Second eng trnsltn:

In the moonlight I felt your heart 
Quiver like a bowstring's pulse 
In the moon's pure light, you looked at me 
Nobody knows your heart 

When the sun is gone I see you 
Beautiful and haunting, but cold 
Like the blade of a knife, so sharp and so sweet 
Nobody knows your heart 

All of your sorrow, grief and pain 
Locked away in the forest of the night 
Your secret heart belongs to the world 
Of the things that sigh in the dark 
Oh the things that cry in the dark
