A Heart Released is a record of passages from the thai monk Phra Ajaan Mun Bhuridatta Thera sermons, made during the years 1944-45 by two monks who were staying under his guidance, and edited by a third monk, an ecclesiastical official who frequently visited him for instruction in meditation. The unusual style of Phra Ajaan Mun?s sermons may be explained in part by the fact that in the days before his ordination he was skilled in a popular form of informal village entertainment called maw lam. Maw lam is a contest in extemporaneous rhyming, usually reproducing the war between the sexes, in which the battle of wits can become quite fierce.
