Larian Studios Forums Divinity - Original Sin Divinity Original Sin - Help/Tips/Tricks How can i start Trial of Ascension?

So i'm standing before broken mirror inside Source Temple and don't see anything i can use.

Backtrack a bit to a large boulder blocking your path north. Look for a button.

Oh, many thanks

Ok, somebody tell me please what to do with the Pillars of Self-Awareness. The book says I shouldn't do the Devotion thing (candles) before completing that. Is there a way to do anything with the pillars without brute-forcing the doors?
