indriya

Indriya (Pali; Skt.) is a Buddhist term referring to multiple intrapsychic processes and is generally translated as "faculty" or, in specific contexts, as "spiritual faculty" or "controlling principle." The term literally means "belonging to Indra," chief deity in the Rig Veda and lord of heaven, hence connoting supremacy, dominance and control.

Indriya (Sanskrit) Power, force, especially with reference to the faculty of sense; sense itself, including the inner or astral organ of sense; also occasionally the number five as symbolic of the five senses. The buddhi-indriyani or jnanendriyani are the five inner organs or faculties of perception: eye, ear, nose, tongue, and skin. To these are added the karmendriyani (organs of action): larynx, hand, foot, anus, and generative parts; between these ten organs and atman stands manas, which thus with the atman and the ten faculties and organs of sense, make twelve divisions of the human constitution. In Vedantic philosophy the four inner organic faculties (antar-indriyani) are manas, buddhi, ahamkara, and chitta.
Each of these fourteen faculties and organs is presided over by its own respective inyantri (ruler): the eye by the sun; the ear by the quarters of the world; the nose by the two Asvins; the tongue by Prachetas; the skin by the wind; the voice by fire; the hand by Indra; the foot by Vishnu; the anus by Mitra; the generative organs by Prajapati; manas by the moon; buddhi by Brahman; ahamkara by Siva; chitta by Vishnu as Achyuta. The differences in enumeration are to be accounted for by the different manners in which the various Indian philosophic schools enumerated and divided the different parts of the human constitution.
In the Puranas seven creations are enumerated, the third being called indriya, or organic evolution. See also AINDRIYAKA
In yoga training restraint of the senses is termed indriya-samyama, while indriyasanga is nonattachment to objects of sense or of the material world.
