Where can you find the eye of truth on the game Zelda Ocarina of Time

To get the eye of truth you have to go to Kakariko Village as an adult after you beat the water temple. When you arrive the town will be on fire and a monster has escaped. Shiek will be attacked and then disappear. go to the windmill and talk to the guy with the funky instrument. He will play you a song for the ocarina. Now after that you go to the Temple of Time and put the Master Sword back on its pedestal to turn into Young Link. Then go to Kakariko Village and play that song the guy taught you in the windmill. The well will dry up so go to the bottom and battle your way through; you will find the eye of truth in there.
