There are two things to consider: the mastery of the mystery itself, and the insight into the mystery, its perception. To gain insight into things the mystic enters into the depths of the whole mechanism of the universe by educating his senses to be keen enough to see and hear the working through it all, through the whole cosmic system. Taking these two senses as his means of investigation he dives deep into the universal life. But there is another way to take, and that is by the power of the word that we utter, which by means of its vowels and consonants enables the mystic to master life. How is it that he can master life by this means? It is because this is the only source of creation. Everything that has been created and then constructed or destroyed has come into being through vibration and through sound, so the mystic considers that this is the chief means for accomplishing everything.
