Virya (Diligence) — The Fourth Paramita

Virya is the fourth paramita, the joyful energy (utsāha) that sustains the bodhisattva across the three incalculable aeons (asamkhyeya-kalpa) required to accumulate sufficient punya (merit) and jñāna (gnosis) for Buddhahood. Shantideva's Bodhicaryavatara devotes its seventh chapter to virya, defining it as delight in virtue (kuśalālasya) and identifying its three enemies: laziness (ālasya), attachment to unwholesome activity, and self-defeating despair. Within the Noble Eightfold Path, virya corresponds to sammā-vāyāma (right effort), which the Anguttara Nikaya specifies as fourfold: preventing unarisen unwholesome states, abandoning arisen unwholesome states, cultivating unarisen wholesome states, and sustaining arisen wholesome states.
