In The Legend of Zelda: Tears of the Kingdom, Zanmik Shrine can be found on a hill overlooking Hateno Village in eastern Hyrule south of Mount Lanayru.
To clear the shrine, you will have to complete the Scoop It Out challenge. To begin, head down the stairs then climb down the ladder on the left. In the middle of the room will be a giant wheel over a ball pit. Head to the far side of the wheel and attach two of the metal squares to it like in the image below.
You’ll then want to pick up one of the balls and stick it to the square. Move another square onto the two conductors on the floor to power the wheel. This will bring the ball to the ramp up top. Unstick it from the square and place it on the floor plate to open the gate.
Head to the altar to receive your Light of Blessing.
