“Heart-Wood from the Bo Tree” is a collection of three talks given by Ven. Ajaan Buddhadasa to the Dhamma study group at Siriraj Hospital in Bangkok in 1961. In these talks the Ven. Ajaan proposes that the “heart-wood” or the pith or essence of the Buddhist Teachings is the practice of non-clinging, the dwelling with a mind empty of the feeling of “I” and “mine”. He masterfully shows how this practice may be developed and how taking emptiness as the fundamental one has a wonderful tool to understand and make use of every one of the many concepts and skilful means that lie within the Buddhist tradition, and also how to distinguish those things that are alien to it. Drawing fluently from material in both the Pali canon and the teaching of the Chinese Zen Masters he makes terms and concepts that often seem dauntingly abstract, immediate and practical.
