Viriya

Energy, effort, persevering diligence. Viriya (Pāli, equivalent to vīrya in Sanskrit) is the fifth factor of the Noble Eightfold Path (sammā vāyāma) and one of the four bases of spiritual power (iddhipāda).

Viriya is not brute force nor tense will. It is sustained energy that drives practice without burning out — like a fire that burns steadily, not a spark that sputters out.

The Buddha distinguishes four right efforts (sammappadhāna):

1. Prevent negative states not yet arisen
2. Abandon negative states already arisen
3. Cultivate positive states not yet arisen
4. Maintain positive states already arisen

In the Dhammapada, appamāda (diligence) and viriya (effort) go hand in hand: appamādena bhikkhave paṭipajjatha — “proceed with diligence.” The lazy one (kusīta) does not progress; the diligent one (ātāpī) reaches the farther shore.

In yoga, vīrya appears as the energy of the committed practitioner — courage, the inner strength that doesn’t surrender to obstacles on the path.
