87. While imperfect mediums pride themselves with the illustrious names - usually apocryphal - that sign the communications they receive, and regard themselves as the privileged interpreters of heavenly powers, good mediums never feel sufficiently worthy of such a favor and always maintain a healthy distrust of the quality of what they receive; that is, they do not trust their own judgment. Since they are only passive instruments, they understand that if the communication is good, they cannot regard it as their personal merit any more than they can be held responsible if it is bad. It would be foolish to believe unquestionably in the identity of the spirits who manifest through them, and they leave the matter to be judged by disinterested third parties without any
more offence to their personal vanity for an unfavorable judgment than an actor would be for criticism leveled at the play in which he or she played a part. Their distinctive character displays simplicity and modesty; they are happy with the faculties they possess, not out of vanity but rather as a means of being useful, which they willingly are when the occasion arises, and without being offended if they are not given top preference.
Mediums are spirits' intermediaries and interpreters; thus, it is the responsibility of the evoker, or even the mere observer, to determine the worthiness of the instrument.
