I think this is about Tarja and Nightwish's breakup. It shows Tuomas is no longer happy with his life, because Tarja was turning away from the band, and he's saying he wants to turn to a child again, because when you're a child, you are innocent of all sin. I think he blames himself for turning Tarja into what she is now, and at the same time, he was glad to let her go, becaue as he said in the open letter to Tarja, they had all been feeling bad long enough. He's also saying how he's still writng music becasue he wants to find his heart again:"The music flows because it longs, for the heart I once had."
