Ether Medallion: In the Light World (make sure you beat at least one Dungeon), go to the Temple where you find the third Pendant. You will see a bridge on the upper-left corner. Use the book and talk to the rock.
Shovel: You know that guy that plays the flute in the grove? The guy that teleports away when you get near him? Mirror warp, and talk to the pig man sitting on the chopped tree. He will give you a shovel.
Flute of Ocarina: After getting the shovel, go back to the Light World and start digging. The perfect place to dig is the upper-left area. Just keep digging until you see a blue thing on the ground.
Get Started: First, play the Flute of Ocarina under the windvane at the center of Kakariko Village. The bird on the windvane will break. Play the Flute again, and the bird will carry you and the screen should show the map of Light World and numbers 1-8. Choose location 6. Lift up the rock on the right, and warp to the Dark World. On the way to the Misery Maze, there's a symbol on the ground, showing the Ether Medillion. Use it and the Misery Maze entrance will appear.
