This is a 'how to' book. It teaches the liberation of the mind, not as a mind-boggling theory, but as a very basic skill that starts with keeping the breath in mind. The teachings here are drawn from the works of Ajaan Lee Dhammadharo (1906-61), one of Thailand's most renowned teachers of Buddhist meditation practices. Ajaan Lee was a forest monk - one who prefers to live in the seclusion of the forest and makes his meditation the central theme of his practice - so his teachings grow out of personal, practical experience, although he also makes a point of relating them to standard Buddhist doctrine.
