As regards the Abhidhamma, this is an exposition of all realities in detail.
'Abhi' literally means 'higher', thus ' Abhidhamma' means 'higher dhamma'. The form of this part of the Tipitaka is different, but the aim is the same: the eradication of wrong view and eventually of all defilements. Thus, when we study the many enumerations of realities, we should not forget the real purpose of the study. The theory (pariyatti) should encourage us to the practice ( patipatti ) which is necessary for the realization of the truth (pativedha). While we are studying the different namas and rupas and while we are pondering over them, we can be reminded to be aware of nama and rupa appearing at that moment. In this way we will discover more and more that the Abhidhamma is about everything which is real, that is, the worlds appearing through the six doors.
