Kah Yah Shrine is a Shrine from The Legend of Zelda: Breath of the Wild. Located on Palmorae Ruins, it is inaccessible until the Shrine quest "A Fragmented Monument" is completed, at which time it will appear behind the mounts. The Sheikah Monk Kah Yah offers a Spirit Orb to Link upon completion of his trial "Quick Thinking".
This trial is Quick Thinking, challenging Link to pass barrels through sets of gates on each side of the room to where the buttons are located. The right button opens the right gate that reveals a chest, while the left button does the same with the left gate. The Small Key to the door in front of Kah Yah's altar is located in the chest at the left side, use it granting an entrance to the altar.
