For the first time in the English language a comprehensive manual of Buddhist meditation known as ânàpànasati (the development of mindfulness of breathing ) is available. Although this manual is primarily intended for the benefit of monks, it will greatly assist laymen, too, who wish to undertake a course of meditation but who do not have the guidance of a teacher. Originally published in Thai, this manual is one of the major works of the Ven. Buddhadàsa Bhikkhu and delivered in 1959 in the form of a series of lectures to monks of Suanmokkha Monastery, Chaiya, Thailand. Ven. Buddhadàsa Bhikkhu, a major voice in the Buddhist world, is an accepted master of Buddhist meditation. In constructive positive language, the manual guides the meditator through the 16 steps of ânàpànasati.
