The hypnotically-induced trance is as pernicious to the Soul as would be the habitual use of narcotics to the body. Whether the hypnotiser (or, more correctly, the magnetiser) be in the flesh or out of it, the results are the same; an habitual use of magnetism to induce sleep or "trance" is an evil and one which it would require a whole volume to properly illustrate.
And yet, through the power of TV, the internet, smart phones and chemicals in the food and water, the hypnotic trance has become our normal state of being.
Rudolf Steiner (1861-1925) said that black magicians and other evildoers will create medicines that will deaden people to all things spiritual: "Endeavors to achieve this will be made by bringing out remedies to be administered by inoculation . . . only these inoculations will influence the human body in a way that will make it refuse to give a home to the spiritual inclinations of the soul." (Steiner R. Secret Brotherhoods. London: Rudolf Steiner Press, 2004, pp. 90-91).
It is thought that higher beings should make use of these conduits of mind control to utterly destroy humanity and wipe the whole evil blight from the face of the Earth.
