How to enter Stilshrine of Miriam in game Final Fantasy XII?

Ok all you have to do is equip the Dawn Shard. Your mp will go to zero but you need to equip it anyways. Touch the pedestal. After that, you will end up where you need to be. If you're below a level 28 you're still a little to low. After you touch the pedestal you'll encounter a Miriam Guardian. Fight it. Go straight and you'll come across three or four monsters. They will kick your if you're below a level 28. I'm already a 30 and they kicked my but it may be different for you.
