[FOREWORD FROM THE FIRST THAI EDITION] This book presents a series of special discourses by Venerable Buddhadāsa Bhikkhu. The discourses were delivered to his student-monks, who were ordained for a limited time. They were somewhat like the last instruction for the monks, before their returning to laity, to take along dhammic concepts and to rightly conduct themselves in the surrounding society. This would bring them peace and harmony with the world. The title of the lecture was Disadhamma, which means the pathway dhamma for mankind. Actually disadhamma is present in various textbooks for Thai students in general. But this particular book, Disadhamma, will describe what is beyond the scope of the textbooks, something different from what most people think of as householders' affairs. Try to read and understand a chapter of it, and you would know that Disadhamma contains important issues and compiles all of the knowledge necessary for dhammic intellectuals who are associated with society. All of the issues are what everyone need to know in order to have a successful life, since they involve people in their daily life. The author said that some people might not agree to what he presented for the monks to think about the disas. But the presentation was just a suggestion. If the monks liked the ideas, they might take them for experimentation. The author's presentation was intended for the audience to know how to do the best and how to get the best benefit from the practice. This would make every facet of life a lesson, so that one's life can be problem-free and perfected. We hope that this book would be something like a manual for one's living as a householder, making his or her life tend to real peace and earning him or her the best thing that a human being should get with meritorious intention.
