The Ministry School features the #4 talk "Why Hypnotism Is Not For Christians". But it is, according the WTS own publications:
First we learn the JW definition of hypnotism:
*** g03 7/8 p. 26 Is Hypnotism for Christians? *** HYPNOTISM has been the subject of much debate and controversy. Even experts in the field find it difficult to explain. It is generally understood that hypnosis is an altered state of consciousness, or trance.
And of course that it is bad (notice the circular reasoning):
*** g74 9/8 p. 28 Is Hypnotism for Christians? *** Whether a Christian will consult a doctor who at times uses hypnosis in treating others must be decided personally. (Gal. 6:5) But a true Christian would not permit it to be employed in his own case. Why? Because hypnotism is not for Christians.
But did you know that God hypnotized people?
*** w52 4/15 p. 247 The Field of Bible Prophecy *** Akin to visions and dreams is the trance . It appears that while in a state of deep concentration of mind or in a sleeplike condition the active force of God superimposes a picture of his purpose or a vision upon the mind of the one so entranced . As in the cases of straight visions and dreams the inspired one is left to describe the vivid revelation in his own words or expressions.*** w97 1/15 p. 31 Enoch?Fearless Against All Odds ***
How was Enoch given a "witness that he had pleased God well"? What evidence did he have? Likely,
God put Enoch into a trance , even as the apostle Paul was "caught away," or transferred, evidently receiving a vision of the future spiritual paradise of the Christian congregation.*** w97 6/15 pp. 4-5 How Did God Inspire the Bible? ***
Visions, Dreams, and Trances.
A vision is a sight, scene, or message superimposed upon a person?s mind while he is awake , usually by some extraordinary means. For example, Peter, James, and John, "when they got fully awake," saw a vision of the transfigured Jesus. (Luke 9:28-36; 2 Peter 1:16-21) In some cases a message was conveyed in a dream, or night vision, being impressed upon the recipient?s subconscious while he was asleep. Daniel thus writes of "the visions of my head upon my bed"?or, as translator Ronald A. Knox renders it, "as I lay watching in my dream."?Daniel 4:10.A person whom Jehovah put in a trance was evidently absorbed in a state of deep concentration, though at least partially awake.
(Compare Acts 10:9-16.) In the Bible the Greek word rendered "trance" (ek´sta·sis) means ?a putting away or a displacement.? It suggests the idea of throwing the mind out of its normal state. Thus, a person in a trance would be oblivious of his surroundings while being fully receptive to the vision. The apostle Paul was likely in such a trance when he was "caught away into paradise and heard unutterable words which it is not lawful for a man to speak."?2 Corinthians 12:2-4.
What's more, here the WTS recommends creative visualization, a form of self-hypnosis:
*** w93 4/15 p. 12 Hope?Vital Protection in a Dismal World *** Further, we should make sure that our hope for the future is not just a vague abstraction. We need to make it real in our minds. Do you hope to live forever in Paradise on earth? Would you like to meet your dead loved ones when they are resurrected on earth? If so, do you picture yourself there at that time? For instance, Isaiah 65:21, 22 speaks of each one building his own house and then occupying it. Can you close your eyes and imagine yourself working on the roof of your new house, nailing down the last shingle? Just think of looking around you at the results of all your planning and labor. The cheery sounds of construction quiet down; you survey the landscape as the afternoon shadows stretch across it. A breeze makes the trees sway gently and cools you from the heat of your work. The laughter of children, mingled with birdsong, reaches your ears. The talk of your loved ones rises from the house below. Visualizing such a happy moment is not idle speculation; rather, it is meditation on a prophecy that is sure of fulfillment. (2 Corinthians 4:18) The more real that prospect is to you, the stronger your hope that you will be there. Such a firm, palpable hope will protect you from feeling "ashamed of the good news," which might make you shirk the assignment of sharing it with others. (Romans 1:16) On the contrary, you will want to ?boast in the hope? as the apostle Paul did, by sharing it confidently with others.?Hebrews 3:6.
Is the WTS is demonizing a concept while embracing the principle?
