The commentaries give a detailed explanation and nomenclature of the different cittas, moments of consciousness, which each perform their own function, and they deal with the different processes of cittas experiencing an object through a sense-door or through the mind-door. Although not all the details concerning the processes of cittas can be found in the scriptures themselves, the commentaries are firmly based on the scriptures. The essence of the subjects explained by the commentaries can be found in the scriptures. The Dhammasangaṇi, which is an analytical exposition of realities, enumerates different cittas arising in processes. The Vibhaṅga, under “Analysis of the Elements”, refers to cittas performing their functions in processes and also the Paṭṭhāna refers to processes of cittas under the heading of some of the conditions it deals with. Moreover, the Paṭisambhidāmagga (Khuddaka Nikāya) mentions (I, Treatise on Knowledge, in chapter XVII, under “behaviour of citta”, viññāṇa cariya) different functions of citta in a process. I hope that these few references show that the commentator did not give his own personal views, but was faithful to the tradition of the original scriptures.
