Jiosin Shrine is located south of Lookout Landing near a chasm in Central Hyrule.
To complete this shrine and reach the altar, you must pass the Shape Rotation challenge. To do this, head down the stairs then enter the room on the right. Use the Ultrahand ability to grab the concrete slab and fit it through the cross shaped hole on the wall. You can then use it to make a bridge and cross the gap in the first room.
In the next room, head through the doorway on the right and use Ultrahand on the two blocks stacked on top of each other. Adjust the block to fit through the opening of the wall then push it through.
Back in the main room, look to the right where you’ll see some ledges with a chest at the top. Rotate the block and place it in the square section of floor then climb up to the chest to find the Hasty Elixir.
You can then grab the cubes and move this through the hole in the wall across from where you first grabbed it. Rotate and place is like show in the image below to reach the ledge allowing you to reach the altar and receive the Blessing of Light.
