The aim of this book is to provide a clear instruction in and reflection on Buddhist meditation as taught by Ajahn Sumedho, a bhikkhu (monk) of the Theravadin tradition. The following chapters are edited from longer talks Ajahn Sumedho has given to meditators as a practical approach to the wisdom of Buddhism. This wisdom is otherwise known as Dhamma, or 'the way things are.'You are invited to use this book as a step-by-step manual. The first chapter tries to make the practice of meditation clear in a general way and the subsequent sections can be taken one at a time and followed by a period of meditation. The third chapter is a reflection on the understanding that meditation develops.
