You can only revisit the temples after you defeat Sin and the dark aeons that
are blocking the entrance to some of them. You have to solve the puzzles
again to gain access to the Chamber of the Fayth. Here, the Fayth will tell
a part of the story about Sin, Jecht and their dream. You´ll receive some
treasures too, which are mostly rare spheres.
