Push the pedestal to start things going. Go left and left. Grab the Bevelle sphere and put it over on the right. Now you've opened up a new path you can take.
Head back around and at the new intersection go north (down). Now go south down again. Grab the Bevelle sphere. Go back up to the middle floor and head to the third junction. Stick the sphere there. A bridge will appear!
Head back to the 2nd intersection and grab the glyph sphere. Now go across the bridge and take the destruction sphere. Put it into the 2nd intersection spot. Now go back upstairs.
Go to the top of the stairs and get the HP sphere.
