One of the seven books of the Abhidhamma Pitaka. It seems to have been designed as a supplement to the Dhammasangani, and discusses, chiefly, the mental characteristics found in converted and earnest persons. It is divided into fourteen sections and possesses a Commentary by Buddhaghosa. Published by the P.T.S.
The Sarvástvádins call the Dhátukathá the Dhátukáyapada. There seems to have existed in Ceylon another work called the Mahádhátukathá, claimed by the Vitandavádins as an Abhidhamma-work, but rejected by the orthodox as uncanonical. DhSA.4.
