This is the first song of Sully's solo album Avalon.
It is also called Avalon.
In his words, the song is about meditation and what you experience during meditation.

Avalon...

A veil of sparkling white soothes and bathes me in the light
It feels me with the suns and visions of the ancient ones

Descend to me, and sooth my disarray
And so it's done-Hear my words Avalon

Fields are swaying like dancers in the moonlight
Rivers field with dreams-Unbroken and still promising

Descend to me, and sooth my disarray
And so it's done-Hear my words Avalon

Warm inside-open the way in
Float into the night-Embrace what's to be
