How do you get 2 the heavens (temple in the sky) I already restored the..

After restoring the girls memory you must go back to the hidden village and show the old woman the Dominion Rod. She will then say you are the chosen hero and give you a book. Then speak to Shad in the basement of the Kakariko Sanctuary and show him the book. He will then say a weird word to the statue but it will not have any effect but it will power up your Dominion Rod. Go to the new marks on the map and fill the sky book.
Hope this helps.

Once you give the Charm back to Ilia, head back to the Hidden Village, show Impaz your Dominion Rod and she'll give you the Ancient Sky Book.

Warp to Kakariko Village again, enter Renato's House, drop down the hole and give the Book to Shad to accidentally power up the Rod.

Continue on with locating the 6 Statues, then when you're done go back to Shad in Kakariko Village!

Go back to the hidden village and show the person living there the dominion rod. They will restore it's power and you now have to go back to Kakariko village. Show Shad the book and he will talk and say some words. Now that your dominion rod is cured, Shad will give you the places where the Owl statues are. Go to each one and step on the symbol to get a letter. When you have found them all go back to Shad to move the Owl Statue. Go down the steps and you will see a big, broken cannon. Tell Shad to go away and then move it to Lake Hylia. Ask the guy to fix and he will... For 300 rupees. Once you pay him he will fix it and you have to clawshot the barrel and you will go inside it.
