Urdhva pundra
A vertical U or V shaped tilak worn by Vaishnava Hindus, devotees of Vishnu and Krishna.
Also: namam, Vaishnava tilak
The urdhva pundra, "upward mark", is drawn from the nose up the forehead, usually as two white lines of clay joined at the bottom, with a red or yellow line between them. Its exact form varies by community: Sri Vaishnavas of South India wear the namam, and Gaudiya Vaishnavas, including those of Vrindavan, draw a narrower form with a leaf shape on the nose. It is worn daily by many devotees and priests.
