Comm. NT: 20. See Abhidhamma Mātikā (“schedule”), Dhs 1f. This consists of 22 sets of triple classifications (tika) and 100 sets of double ones (duka). The first triad “profitable, unprofitable, and [morally] indeterminate,” and the first dyad is “root-cause, not- root-cause.” The Mātikā is used in the Dhammasaṅgaṇī (for which it serves as the basic structure), in the Vibhaṅga (in some of the “Abhidhamma Sections” and in the “Questionnaires”) and in the Paṭṭhāna. All dhammas are either classifiable according to these triads and dyads, under one of the headings, if the triad or dyad is all- embracing, or are called “not-so-classifiable” (na-vattabba), if the triad or dyad is not. The four triads mentioned here are: no. 13, “dhammas with a limited object, with an exalted object, with a measureless object”; no. 16, “dhammas with a path as object, with a path as root-cause, with path as predominance”; no. 19, “dhammas with a past object, with a future object, with a present object”; and no. 21, “dhammas with an internal object, with an external object, with an internal-external object.”
