Do you have to play The Witness twice to solve the last puzzle

the-witness

This whole question is a spoiler, so I ask it all hidden:

When you start the game, the tower at the exit gate of the first castle is glowing white, so you can solve that puzzle. But once you solve the puzzle to open the gate, it stops glowing and you cannot solve that puzzle any more and cannot finish the monolith in the village.C

Do I have to solve this puzzle right at the start to be able to solve the monolith in the village?

Or is there a way to reactivate the glowing gate-pole?

Best Answer

Yes, you can reactive the glowing gate.

In the cave-system leading to The Challenge, you find sheets of paper with the same pattern as the the puzzle next to the gate. Enter that pattern to reactivate the gate.
