Riddle in Verse

Fire forms stone and pure white light,
Banishing shadows of the night.
I am the lit path edgéd in shadow,
The guide whose past will ne'er show.
Walk me true, straight and free,
And ne'er again 'lone you'll flee.
I am that which binds and bonds,
Fiery healing and pain make songs;
Wishsong cries out for light's joy,
As misery's end inspires soliloquy.

What am I?

When the right answer has been guessed, I will let you all know. I have a full explanation ready, just in case it's difficult to decipher the meaning of the riddle even with the answer to hand.

I am aware that there is at least one place that houses this riddle (since I put it there myself) on the Internet, but rather than spend hours searching, I suggest you use the time attempting to decipher it.

Enjoy

Oh, and... sorry if the rather archaic phrasing confuses you. It's the thoughtform I write verse with, and converting it to modern English breaks the flow and rhyme. I like my riddles to flow and rhyme.

Lastly, I'm new here (hi!), so bear with me if it takes me some time to be accustomed to the site fully.
