Note that every organization in the world has it's dissenters. TM is no different. Some people protest altruism (read Ann Ryand), others protest individualism (read Karl Marx).
I'm sure the individuals feel sincere in their complaints. No problem. The one thing to remember is "balanced reporting". Check other sources, including the www.tm.org and www.mum.org sites. (Well, do a search on Transcendental Meditation.) There's a reason why "science" is useful. It puts to the test any claims someone makes.
TM has passed the tests that show psychological improvements in practitioners. Also, the scientific method serves to weed out idiosyncrasies that will happen to people at random. If out of 1000 people who start a diet of yogurt and celery, 3 get cancer, does that means you should never eat yogurt and celery together? Would those three get cancer anyway? (Pobably yes, given the incidence of cancer in our population).
Common sense says "check it out in a group test". That's what science does. TM has passed the science test. I'm not sure the TM ex people pass that test when it comes to labeling TM a "cult". The definition of "cult" includes prohibitions on members to examine critically their organization. Maharishi is the first to say "examine TM for what it offers or doesn't offer you personally. Examine it scientifically."
Flame on, TMexers. The truth is available. Contrast makes the truth more visible.
