- One of the seven universa mental factors within the Theravada abhidharma teachings.
- One of the components in the jhānas.
Nina van Gorkom explains:
- This concentration, known as one-pointedness of mind, has non-scattering (of itself) or non-distraction (of associated states) as characteristic, the welding together of the coexistent states as function, as water kneads bath-powder into a paste, and peace of mind or knowledge as manifestation.
For it has been said: 'He who is concentrated knows, sees according to the truth.' It is distinguished by having ease (sukha) (usually) as proximate cause. Like the steadiness of a lamp in the absence of wind, so should steadfastness of mind be understood.
Ajahn Sucitto explains:
- This is the factor of absorption that arises dependent on bringing to mind, non-involvement and evaluation. It occurs in meditation when the quality of ease has calmed rapture and the mental energy; the energy of focusing and the bodily energy are in harmony. The resultant merging of mind and body is experienced as a firmness in awareness, which is hence not penetrated by sense-impressions.
