Capítulo 104: 116. Know Yourself

Mack felt as if drunk while fighting, but for the first time he understood something, Essence flowed like water, like a virus it infected everything, it resonated with the will of things, and the stronger a emotion the stronger the will, if he wished to use it better he had to let himself loose. 

All that come to him because a single word .... Drunk...  Because people often got stronger while drunk Mack's mind started to race to conclusions as thoughts flashed to his mind.

He always thought that the gates at the tower had the aim to make his will stronger by shutting down his own emotions, by not letting them get over his real thoughts, but he was wrong, now he finally realized that they true goals was to make him grasp the edges, to know himself, to accept himself and his own past and problems and utilize that to his own advantage.
