The final book of the Abhidhamma-piṭaka, divided into two parts: the Tikapaṭṭhāna with “groups of three”, and the Dukapaṭṭhāna
dealing with “groups of twos”. It is a highly technical text, consisting of a minutely detailed analysis of the doctrine of conditionality.
Translation: Conditional Relations, Vols. I and II (translation of part of the Tikapaṭṭhāna only).
ed. Mrs C.A.F. Rhys Davids
