The Hover Stones in this room will stay in their position as long as they are powered on. Use Ultrahand to move a Hover Stone in front of the ledge, then use Ascend on the Hover Stone to get on top of it and go onto the ledge.

In the next area, there is a piece of metal leaning against the wall. Attach it to the top of the Hover Stone and hit it to activate the Hover Stone, then place the bridge in the gap so that you can walk across it.

In the area after that, take the bridge and rotate it to turn it into a ramp up to the next area.

In the next area, use Sensor + to find a ledge that has a treasure chest on it. Use a Hover Stone to Ascend up to that ledge, and open the chest to get 5 arrows.

Then look for the glowing orb, and place it (don't attach it) on top of the Hover Stone that is in front of the stone square. Stand on the Hover Stone as well. Then hit the glowing switch next to the stone square, and it will push the Hover Stone forward. This will propel you and the orb across the gap. Place the orb in the floor switch if needed, then go through the bars and check on the dragon ring to get the Light of Blessing.
