As Buddhist meditation becomes more popular, it is vital that clear and accurate guidance is available. For many years, there has been an unfortunate lack of thorough instruction in simple English on the deeper states of meditation called Jhanas. Even though the Jhanas are, perhaps, the theme most repeated by the Buddha in the Suttas, and in spite of the fact that the old teachers of the Thai forest tradition encouraged, preached and taught Jhanas, a description of their development is hard to come by. This ebook, then, serves to remedy this lack of practical information. It aims to describe the path into Jhanas, the characteristics of Jhanas, and the relevance of Jhanas to insight and Enlightenment. Without any appreciation of Jhana, one’s understanding of Buddhism is incomplete.
