Preparations
Various temples within the game contain "Destruction Spheres" in puzzles. Once you have all of them, board the Fahrenheit airship and input the coordinates 11 to 16 for "X" and 57 to 63 for "Y." This will allow you to find the temple. Equip the characters Wakka, Rikku and Titus with any armor that has "Stoneproof," "Curseproof" and "Deathproof."
Finding the Statues
After jumping into the water, you will find the boss Geosgaeno. This boss will have around 35,000 hit points and you will need to use the three equipped characters to fight him. Once he is defeated, continue swimming and you will end up in the temple. Start walking down the path.
Statue Layout
The statue layout, from the bottom right to the top left, must be Kilika, Djose, Bevelle, Zanarkand, Macalania and Besaid. If any of the statues don't light up, it means you missed a Destruction Sphere and will have to go back and get it. Use a destruction sphere to break the seal and you will gain Anima.
