I stumbled across this little book in the 1970's and have been recommending and sending it to friends, relatives, and acquaintances ever since. It is what it is: an introduction to meditation for beginners and the curious. It is simple, straight-forward, practical, unpretentious, and easy to read and comprehend. Therefore, it is the perfect starter book. It offers an introduction to a variety of meditative techniques but, rather than advocating any of them, urges readers to experiment with the different techniques until what is most comfortable and/or productive for them. After reading it and determining a favored technique, the reader can move on to something heavier. One of the things I have always liked about LeShan is the fact that, in this book, he acknowledges some of the more (potentially) startling by-products or side-effects of meditation but does not emphasize them. This may be a disadvantage as well as an advantage, but this is an introduction to some meditative techniques, not an encyclopedia of meditative practices.
Anyone interested in exploring meditation should have this book and give it a try. Since it was written there has been considerable research into the benefits of anti-stress practices. The medical community is beginning to catch onto the non-intrusive, non-addictive, non-injurious benefits of meditation as an antidote to stress. Perhaps you should, too. With this book and some practice you can learn to take a chill instead of a pill. And if it does not offer enough for you, at least it provides some direction to finding out what will be.
Read the book. Practice the techniques for a month or two. The benefits from the breathing exercises alone, if you honestly and consistently apply them, will lead you to extoll the virtues of this little, big book that is still influential more than twenty-five years after it was first published.
