This has to be one of the most comprehensive yet easily accessible books on mediation out there. Really I cannot recommend this enough. I have been meditating for over 20 years now and this book helped me understand why I do certain things, what other techniques I can use to deepen my practice as well as what to do when the invitable dry spell arrives, and all without force. For the beginner too there is plenty to get you started along the right track, as well as helping you find the style of meditation which works for you. Brilliant!
