It was the night after Luke got pardoned, and Ben went to the Fallen Jedi Room to see his mother's lightsaber. When he got there he knelt before her grave and said, " While I was away mom I wrote something for you? I hope you enjoy it."
"The fire in the candleholder is the fire that grows inside of you. As you grow the fire in the candleholder grows too. It is also the dreams that you grow up with. These fires are the dreams that you want to come true. When the fire in the candleholder goes out, your dreams come either came true or your time ran out."
After he finished he heard a voice from behind him, "your mother would have loved that poem son, and I love it too."
Ben turned his head and saw his father behind him with a smile on his face. Then Ben said, "Can we have peace now dad?"
"Yes, Ben we can." And then Luke helped Ben get up and Luke wrapped his arms around his son and just held him for a few minutes.
