How to get through the stilshrine of miriam?

First equip your party leader with the Dawn Shard, touch the first switch that is in the middle walk way cross over near the front of the temple.

You will find your self in the back, follow the path alone and do the logical thing. You will reach the end, and when you try to open a door back there, a door at the front of the building will work. Thankfully in the next room over there is a teleporter back to the back of the front room. Go to the newly opened door, walk through it and wind youself through this maze and you will find 3 statues. Make all of them point to the large statue. There is a small boss fight near the end of all the hallways and the boss is magnetic so make sure you take off all the fancy metal armor for some cotton robes and other things. Now that the 3 statues face the giant statue, the door, way in the back that blocked you last time, is open. Again, thankfully the exit to this hall way on the other side is close by and you can use the back teleporter to go 1 room away from the newly opened door.

Continue straight on and 2 rooms later you fight an Ice Esper, so remember to unequip all your ICE ELEMENT weapons for other ones (and also remember to put back on your good armor.

I tried to condense my version. It's hard to show without extremely long winded paragraphs or a map.

Only weird things are the dawn shard needs to be equiped to your party leader to do anything and the statues must be turned to face the big one.
