Gambier Bolton, Robert – The Conditions needed to obtain a materialisation – 07 Do not use hypnosis, it results in materialisations that are conjured entirely from the perceptions of the sitters or sensitive
Type of Spiritual Experience
Of course that is what may be aimed for. But the dangers may be that a materialisation is taken for the 'real thing'
A description of the experience
Robert Gambier Bolton – Ghosts in Solid Form
Hypnotism in any shape or form should be strictly forbidden in connection with such delicate experiments as those under consideration; and to deliberately place a Sensitive under hypnotic influence at the commencement of an experimental meeting, instead of permitting him to pass voluntarily into genuine trance is simply courting disaster so far as results are concerned.
This has been proved conclusively in France and Germany recently, where on passing a Sensitive for materialisations into the hypnotic sleep, the forms issuing from the Sensitive in many instances so strongly resembled illustrations in current numbers of local newspapers —which had been seen by the operator or some of the experimenters (or both), and had deeply impressed themselves upon the brains (and minds) of those present — that whilst more advanced investigators at once discern the cause of the trouble, the vast majority, in a state of utter bewilderment through their inexperience, put the results down to fraud on the part of the entirely innocent Sensitive.
