People will do anything, no matter how absurd, in order to avoid facing their own souls. They will practice Indian yoga and all its exercises, observe a strict regimen of diet, learn 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. Thus the soul has gradually been turned into a Nazareth from which nothing good can come.
