scientists studied people who meditated, and learned that tm really did help them to relax, and to think more clearly. a few christian ministers and writers denounced tm, calling it "a into eastern religions", and said that mantras were really a way of invoking the devil or demons. other christians saw no harm in it, or encouraged people who wanted to meditate to instead chant the name of jesus christ, or a name for god, or a line from a psalm or christian prayer. in any case, tm went on to help many people around the world, and it is still taught as a form of meditation.
