Long or Wide
Pull back on the stone paddle until it won't go any farther, then let go. It will hit the large orb, which will slide along the rails and fall into the floor switch, opening the bars to the next area.
In the next area, attach the metal cube to the back of the stone paddle, then pull back on it and push it up and let go as before. The increased weight of the paddle will be enough to make the orb go up the curved rail and into the floor switch.
In the final area, take the long metal slab and attach it to the back of the stone paddle, then pull up on it and let go to slide the orb into the floor switch. A door will open, and a rail cart will come out.
Eventually, the cart will fall onto the lower rails, or you can just move it there with Ultrahand. Then take the long metal slab and attach it to the side of the stone paddle so it is behind the cart and near the floor. Get in the cart and push back on the metal slab, then let go so that it swings and hits the cart. Use Ultrahand to take the treasure chest along the way. You can use Recall on the cart if you miss the treasure chest. It contains a Sneaky Elixir.
From there, go to the end of the shrine and check on the dragon ring to get the Light of Blessing.
