If you had the power that mesmerism gives to influence minds wrong as well as right, the science herein explained would take it away. To control minds with sinister motives, or in any but a right direction, would destroy your position in science. Influence the minds of others from motives of selfishness, revenge, impurity, or any bad motive, and you would lose your ability to heal in science, and never regain your position until you had suffered sufficiently from this error, to forever destroy it, and not venture again on ground so dangerous. A mal-practitioner can never reach the standard of scientific healing. It would be as impossible as for a camel to go through the eye of a needle. (Eddy, Mary Baker, Science and Health, 1st, ed., p.376-377)
