I can't recommend this book highly enough. So easy to read and understand, I couldn't put it down till I'd finished reading it. The explanations are so easy to deal with, all in all I love it.
Using a straightforward style of presentation the Author provides all you need to know to become free of stress and worry through the "simple and beautiful act of sitting quietly, alive to the breathing". as taught by the Buddha.
I first found the book 20 years ago when visiting Thailand.
This is the new revised edition, basically a larger format and larger print.
The Author Buddhadasa Bhikkhu (passed away in 1993) is perhaps the most influential Buddhist teacher in the history of Thailand. In 1932 he founded Wat Suan Mokkha-blarama, on of the first forest monasteries in Thailand.
