Games: How Do You Get Into the Boss Room in the Spirit Temple in Zelda: Ocarina of Time?

Enter the Colossus room featuring an enormous statue of a meditating woman with a lower half resembling a snake.

Climb either set of stairs in the back corners of the room to the top, pull out your Longshot, and fire it at a chain supporting the hanging platform in the middle to pull Link over to it.

Stand in the beam of sunlight on the platform and turn link to face the head of the Colossus. Hold "R" and "Z" to stand with your Mirror Shield deflecting light into the face of the statue, causing it to crumble and revealing a door.

Fire your Longshot at the metal grate of the door behind the Colossus' face to drag Link into it. Walk through the gate, which opens automatically, to encounter Koume and Kotake in the next room, along with a brainwashed Nabooru.

Fight Nabooru, who is wearing the armor of an enemy Iron Knuckle and defeat her. A good tactic is to press "Z" to Z-target Nabooru, press "A" to perform a jumping slash and then press "away" on the thumbstick and "A" to backflip to a safe distance. Repeat this process repeatedly to dispatch the enemy quickly.

Enter the door at the back of the room that leads to the Boss room of the Spirit Temple.
