Cover art for Oasis lyrics by Tarja Turunen

I think this song is about suicide.All of its lyrics refer in a way to it

"The shadow of goodness covers the tear," The character thisnks he is dooing good,hence the Shadow of good "Peace may, rock the cradle to sleep." peace achived by him commiting suicide,and "the cradle rocking him to sleep" is him dying. "Hope remains, a way to love."

Hope has remained that he will be loved some day in the other world." "A way to a deep freedom." He has freed his soul of his earthly cage and now is free.

At least this is how i see it.
