"The Mystical Life Is The Centre Of All That I Do"

I recall many times when scholars of Yeats or school and college teachers (including some of my own) have glossed over his occult involvement, sometimes stating that it was little more than a "phase" or some other irrelevant trifle that just happened in his life. I believe the following quote from the man himself should dispel this common (and highly irritating) notion:

"If I had not made magic my constant study I could not have written a single word of my Blake book, nor would The Countess Kathleen ever have come to exist. The mystical life is the center of all that I do and all that I think and all that I write."

- W.B. Yeats
