How do light up all 6 torches in Zelda and the windwaker?

You must get the Fire Arrows. To get the Fire Arrows you must get to the part of the game where Tetra is turned into Zelda. After that cyclone to Mother & Child Isles. You MUST use the cyclone. Mother & Child Isles is south 2 squares and east 1 square from Forsaken Fortress.
