Knowing that reliable information on the practice of insight meditation was much needed by practitioners in the West, the renowned Burmese master Ledi Say?daw wrote the "The Manual of Insight." He covers many topics, such as the distortions of perceptions, the Noble Truths, the higher knowledges, Nibb?na, and others, fully expounded and furnished with brief descriptions, some of which are drawn from the Pali texts, while others are the product of Ledi Say?daw's own teachings.
