Ajahn Chah was a master at using the apt and unusual simile to explain points of Dhamma in a memorable way, sometimes to answer questions, sometimes to provoke them. He was especially talented at exploiting the open-ended nature of the simile—in which some similarities are relevant and others are not—using a particular image to make one point in one context, and a very different point in another. This book is a companion to In Simple Terms, an earlier collection of similes drawn from Ajahn Chah’s transcribed talks. Here, the majority of the passages come from a compilation made by Ajahn Jandee Kantasaro, one of Ajahn Chah’s students, entitled Khwaam Phid Nai Khwaam Thuuk (What’s Wrong in What’s Right). The title of this compilation is taken from a phrase that Ajahn Chah often used to describe the misuse of correct knowledge. Ajahn Jandee, in his introduction, illustrates the principle by telling of a man he once encountered who used the teaching on inconstancy to justify the fact that he never cleaned his truck.
