Vasubandhu in his treatise "Abhidharmakośa" defines that Abhidharma "is a pure knowledge together with accompanying dharmas". A "Pure Knowledge" is knowledge firstly about the highest dharma, i.e. Nirvāṇa, secondly about dharmas with a meaning "elements" or "manifestations of elements" to which is divided all empirical existence, all the existence we can experience or think of.

Kleśas (Sanskrit: kleśa; Pāḷi: Kilesa), in Buddhism, are mental states that cloud the mind and manifest in unwholesome actions. Kleśas include states of mind such as anxiety, fear, anger, jealousy, desire, depression, etc. All Buddhist schools teach that through Tranquillity (Śamatha) meditation the Kilesas are pacified, though not eradicated, and through Insight (Vipassana) the true nature of the Kilesas and the mind itself is understood.

Indriya (literally "belonging to or agreeable to Indra") is the Sanskrit and Pāḷi term for physical strength or ability in general, and for the senses more specifically. The term literally means "belonging to Indra," chief deity in the Rig Veda. In Buddhism, the term refers to multiple intra-psychic processes and is generally translated as "faculty" or, in specific contexts, as "spiritual faculty" or "controlling principle."
