We are to be on guard against Satan's deceptive arts. He will take possession of human bodies, and make men and women sick. Then he will suddenly cease to exercise his evil power, and it will be proclaimed that a miracle has been wrought. We need now to have a true understanding of the power of Jesus Christ to save to the uttermost all who come unto Him.... MM 110.4
Men and women are not to study the science of how to take captive the minds of those who associate with them. This is the science that Satan teaches. We are to resist everything of the kind. We are not to tamper with mesmerism and hypnotism— the science of the one who lost his first estate and was cast out of the heavenly courts. MM 110.5
The science of a pure, wholesome, consistent Christian life is obtained by studying the word of the Lord. This is the highest education that any earthly being can obtain. These are the lessons that the students in our schools are to be taught, that they may come forth with pure thoughts and clean minds and hearts, prepared to ascend the ladder of progress and to practice the Christian virtues.—Manuscript 86, 1905. MM 111.1
