A guide on how to find and complete the Sho Dantu shrine and solve the "Two Bombs" puzzle in The Legend of Zelda: Breath of the Wild.
Location of Sho Dantu Shrine
Sho Dantu Shrine is northwest of Gerudo Tower, south of Meadela's Mantle and west of Sapphia's Table.
How to Open Sho Dantu Shrine
You will find a shrine platform with a sign next to it that says to offer a glowing blue stone. You can hit the Luminous Stone Deposits around the platform to get Luminous Stones, then drop one on the shrine platform to make the shrine appear (even if the Luminous Stone isn't glowing).
Two Bombs
To complete the shrine, turn left from the entrance elevator to find some wooden crates in the doorway. Break them with a bomb, then go through to find a piston going up and down. Place a square bomb on it, then when the bomb is next to the metal cage up above, detonate it to activate the crystal switch in the cage. This opens a door next to the entrance elevator of the shrine. Before you leave this room, go around the back of the stone column that the metal cage is on top of, to find a treasure chest that contains a Silver Rupee.
Then go back to the entrance elevator and go through the door next to it that opened. There is another stone piston, but it's not moving. Go around the back of the stone column to find a crystal switch. Place a square bomb next to the crystal switch, then go around and place a round bomb on the the inactive piston. Switch your rune to square bombs and press L to detonate the bomb next to the crystal switch, then switch your rune to round bombs and press L to detonate the round bomb when it is next to the metal cage. This will open the door across from the entrance elevator.
Go through the newly opened door and you will find two angled pistons. Place a square bomb and a round bomb on one of these angled pistons. The piston will launch both bombs toward a crystal switch. The square bomb will land next to the crystal switch, but the round bomb will keep going back and forth between the two pistons. Stand on one of the glowing squares on the floor near the door where you entered this room, switch to the square bomb rune, and detonate it. This should raise you up to the door, but this also places bars in front of the door. Walk onto the solid metal floor between the two platforms that went up, then watch the round bomb, switch to the round bomb rune, and detonate the round bomb when it's near the crystal switch. This will open the bars. Talk to Sho Dantu to complete the shrine and get a Spirit Orb.
