Mesmerization is pleasant. We seek it constantly; in education, in religion, in sports, in entertainment, in commerce, in art, in romance, in travel.
A mesmerizing fellowship can be quite pleasant (e.g. read the Bible over and over… round-and-round, up-and-down). Oops.
Mesmerization must be pleasant for all parties, or it must be dispelled. For mesmerization is no excuse in the law.
