 The term lakṣaṇa/lakkhaṇa means a mark, or a specific characteristic that distinguishes an indicated object from others. The Logicians use this term in the sense of “definition” of a concept or logical category. The Abhidharma applies it to the practice of the discernment of dharmas, distinguishing between multiple generic characteristics a dharma shares with other dharmas and (at least) one particular inherent characteristic that defines a dharma as that very individual occurrence distinct from any other instances of its type. The post-canonical Abhidharma thus assimilates the concept of the particular inherent characteristic with that of intrinsic nature. “Dhammas,” the Theravādin commentarial literature states, “are so called because they bear their particular inherent characteristics” (Vibh-a 45; Vibh-mṭ 35; Paṭis-a I 79; Vism XV 3), and a particular characteristic “is the intrinsic nature that is not held in common by other dhammas” (Vism-mhṭ II 137). Used in conjunction or interchangeably with intrinsic nature, the particular inherent characteristic constitutes a dhamma’s unique definition (Vism VI 19, 35). It is an epistemological and linguistic determinant of a dhamma as a knowable instance that is defined by a distinct verbal description.
