Partial answer:

The Entrance to the Catacombs (the prequel to this puzzle) had the answer SIX. Groups of six with a closed eye together hint at Braille. Interpreting 1 as a bump, we get the message:

THE GEMS OF FOUR SHOW YOU THE WAY BUT THESE OF SIX BEHOLD THE NUMBER

So... I guess we need to divide the letters up into groups of four somehow to get the right path, and we take door 1 on that path.
