Press the button on the left first, to let Riju join you. There's a hole in the wall where bricks can be removed with Ultrahand directly in front of you, and the light you need to hit on the right. Drop down and Hive will start dropping Gibdo, so charge up Riju's lightning to destroy it. if you look down you'll see a Gibdo hive and a tomb. This area will be particularly dark if you're not using a torch, but you can see two paths on either side of the room. Just continue to follow the path after defeating it, to enter the next section of the temple. As you start down the corridor, another Gibdo will appear. This will allow Riju to join you and open up the next room. Turn off to the right at the end, to enter another room with a button to step on. Use Recall on the fireball, to send it back from where it came, and run up the path behind it. Go through the open gate and into a room where fireballs will start to roll down the corridor and land in the pit below.

On the other side, press the button in the right corner of the room to open the gate and turn the flames off. Just get as close as possible to the flames, then dash forward as soon as they go off.

Riju will say you can't make it through the flames, but you can with the right timing. There are Gibdo on the floor here, just before you reach the flames, that you'll need to take care of. Use Ascend to go back up and toward the flames.
