Now I hide away my pain, floating in the purifying wind
Listening only to its gentle sound with eyes held softly shut

I was lead here by a holy song to tread the path of falling lights,
To glisten on to eternity in dreams, where even sadness is wrapped in light

I hug my knees tightly to my chest, and then close up the frigid door
With hands thrown out wide apart I will caress you gently with my voice

I was lead here by a holy song to tread the path of forever falling lights,
To glisten on into eternity in dreams, where even sadness is wrapped in light

My heart floats, purified in heaven's glow
I will continue to wait here for you

There's no limit to our tender love, in the transparent memories I hold close
Even as I try to wipe away the overflowing droplets to show you

This music video for this is gorgeous, so if you're looking for something nice you might want to check it out. They've also got some nice traditional touches, like the masks and fusuma, along with Isshi's demon/courtesian costume
