Shade wrath of angels guide

I have plated this game upto crescent of darkness level. But there when I climb on to the pillar, I could catch the wall point but I cannot get on to the wall. there I can find a stone kept on the wall, which restricts to climb over it. I searched whole room for other option or way, but I could not find any way for further game to play. So please anyone help me to continue in my game.
