This small book represents the wish of some of those fortunate enough to have received Dhamma teachings from Venerable Ajahn Sumedho to share them with others. The first section describes what taking the Three Refuges in the Buddha, Dhamma and Sangha means; and the second section is composed of passages from three or four different talks on the subject of Mindfulness of Breathing. Lastly, the book discusses happiness, unhappiness and Nibanna.
