Indriya
Indriya (literally "belonging to or agreeable to Indra") is the Sanskrit and Pali term for physical strength or ability in general, and for the senses more specifically. In Buddhism, the term refers 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 the Trāyastriṃśa heaven (also known as Śakra or Sakka in Buddhism) hence connoting supremacy, dominance and control, attested in the general meaning of "power, strength" from the Rig Veda.
In Buddhism, depending on the context, indriya traditionally refers to one of the following groups of faculties:
- the 5 spiritual faculties
- the 5 or 6 sensory faculties
- the 22 phenomenological faculties
