Guide to Tipitaka
Canonical Pâli Buddhist Literature of the Theravâda School
Part III - Dhatukatha Pali
Although this third book of Abhidhamma Pitaka is a small treatise, it ranks with the first two books forming an important trilogy, which must be thoroughly digested for the complete understanding of the Abhidhamma Vibhahga, the second book, has one complete chapter devoted to the analysis of dhatus, but the subject matter of dhdtu is so important that this separate treatise is devoted to it for a thorough consideration The method of analysis here is different from that employed in the Vibhanga
Dhatukatha studies how the dhammas listed in the Tikas and Dukas of the Matika are related to the three categories of khandha, ayatana and dhatu m their complete distribution i.e , five khandhas, twelve qyatanas and eighteen dhatus These are discussed in fourteen ways of analytical investigations which constitute the fourteen chapters of Dhatukatha.
