The mystic must beware of the effusions of his all-too-vivid imagination. The confusion wrought by those earnest but inexperienced aspirants who associate their wrong intellectual beliefs, their narrow emotional prepossessions, and their foolish hopes with the Overself's inspiration is immense. They enthuse about what is inconsequential and neglect what is important. So long as they insist on taking the imaginations they revel in so uncritically as a basis for the understanding of life, so long will that understanding itself remain shallow and inadequate. So long as they are less interested in the pure experience of the Overself and more in the fanciful drapery which the mental complexes unconsciously wrap around it, so long will their knowledge of divine matters be halting and uncertain. An unexamined and uncriticized mysticism, which carries a heavy cargo of wishful thinking, is not good enough.
