This is a clear and in-depth description of the jhanas, the traditional Theravadan meditation practice, from two authors who have practised these meditations in retreat with and under the close guidance of one of the great modern masters. Pa Auk Sayadaw is the abbot of Pa Auk Monastery in Burma (Myanmar) and the successor to Mahasi Sayadaw (d. 1982), who has several well-known books in English and who was a spiritual mentor to numerous American Buddhist teachers, including Jack Kornfield, Joseph Goldstein, Rodney Smith, and Sharon Salzberg. He is considered by many to be the leading teacher of the jhanas. The authors describe the techniques and their results, based on their own experience. This helpful book will be appealing to anyone who wants to learn more about this type of meditation. The instructions are thorough and detailed and will help even experienced meditators who have done retreats at one of the many popular Buddhist centres where concentration meditation is taught.
