Grab the statue that is closest to Shiva (the one that is standing on the straight line) and push it to the other side. Go to the left and push it around the circle. Position it just before you reach the straight line. If you move it carefully there, the ray of light will fall on the fan and it will reflect on the crystal.

Now go to the other statue. Stand having Shiva on your left. Push the statue around the circle and continue pushing it along the straight line. When you reach the other side of the circle, go to the left of the statue and push it just a bit. You will again see the ray of light falling on the fan. It will then reflect on the crystal.
