I will admit that I have tried other methods that are very similar to TM, with little/no results. Yes, TM costs while others are free. The meditation itself can be explained in a few sentences. BUT, the explanation of why TM works and how TM works is key and other similar methods do not provide that. Once I learned the how & the why, then I realized that the cost was quite fair. Perhaps even a bargain. Other methods can certainly put you on the "right track," the issue is that the track is long and winding, with peaks and valleys, and obstacles etc., in other words you need a guide. TM is the guide. Go ahead and climb the Himalayas without a Sherpa. Good luck, but don't be surprised when you have no idea how to avoid falling off that cliff.
