Make sure you’ve opened all the gates in this area.

This puzzle is relatively difficult to spot.

It is made of concrete.

You start in the jungle, but near the river.

If you're in the jungle and you've already completed all the jungle puzzles, there will be a wall blocking you. (Jonathan, why??) So, instead you'll have to exit the jungle and walk around to re-enter on the river side.

Walk up onto the rocks until you can see the zen garden area below you.

Find the right angle to combine a curved edge on the rock platform and the path below make the puzzle.

Look from a high place...

towards the monastery.

But first you have to walk a long way from the obelisk area.

Look down onto the little garden near the monastery.
