People will do anything, no matter how absurd, in order to avoid facing their own souls. They will practise Indian yoga and all its exercises, observe a strict regimen of diet, learn theosophy by heart, or mechanically repeat mystic texts from the literature of the whole world—all because they cannot get on with themselves and have not the slightest faith that anything useful could ever come out of their own souls.

– C. G. Jung from The Collected Works of C.G. Jung
