Palithna Mapatuna, who was closely associated with Kheminda Thera and being influenced by Ven. Ñāṇavīra’s writings (and also meeting him personally), prepared 190 pages book Key Elements of the Buddha’s Teaching. It is simple basic and systematic summary of the Dhamma, the Four Noble Truths. In this analysis he explains the main Buddhist teachings: five aggregates, structural hierarchy of experiences, depended origination, views, seven purifications and liberation. It is recommended reading especially for the beginners.
