It looks like you meant “Vihār” (often written vihar).

In Jain Dharma, Vihār means the disciplined movement and residence of monks and nuns (sādhus–sādhvīs). Key points:

• Meaning: “Vihār” = moving from place to place and residing with strict care for ahimsā.
• How they travel: always on foot, only in daylight, attentive to avoid harm to even the tiniest beings.
• During monsoon: they stop traveling and stay in one place for about four months. This is the period of Chaturmās, observed by both Śvetāmbara and Digambara traditions.
• Laypeople: sometimes people say “tīrth‑vihār” for visiting Jain pilgrimage places, but the precise term for lay pilgrimage is “tīrth‑yātrā.” “Vihār” mainly refers to ascetic movement.
