Summary: The lakkhaṇamātikā is the fourth matrix in the Dhātukathā. It provides a list of terms related to the identifying characteristics of phenomena, which are then analyzed through the text's relational operations. (Dhk 1.4)
Canonical locus
The Dhātukathā introduces this matrix after the method and internal matrices, setting up a specific set of doctrinal markers for analysis. (Dhk 1.4)
Dhk 1.4 (dt1.4:1.1)
Sabhāgo, visabhāgo.
>
"With common characteristics, with different characteristics."
Analysis
This matrix focuses on the "nature" (sabhāva) or "characteristic" (lakkhaṇa) of things, but limits itself to the minimal pair of whether phenomena share common characteristics (sabhāga) or have different characteristics (visabhāga). The lakkhaṇamātikā organizes these identification points so they can be tested through the text's relational operations. (Dhk 1.4)
By isolating this minimal pair of characteristics, the Dhātukathā moves beyond mere lists of things to an analysis of the "qualities" that define the Abhidhamma's atomic reality. (Dhk 1.4)
Textual notes
- The lakkhaṇamātikā is relatively short compared to the external matrix but is vital for the text's internal consistency.
- It reinforces the Abhidhamma principle that reality is composed of distinct properties, each with a verifiable nature.
