Did you ever find the 6th container? I have found 3 in the place with symbols on the floor and spikes on the walls and 2 in the place with the moon symbols all over the palace and the wheel thing, which means I am missing one as well. Please could you help me if you know the answer to this?
One is hidden in the Temple of the Seventh Moon (the area with the moons in it). When you click the strength wheel and it starts to spin, move really quickly to the left and you'll see it in the window of the house on the left.
