The Urdhva Pundra is a tilak worn by followers of the Hindu sect Vaishnavism to show that they are devotees of Vishnu. It is generally worn on the forehead, but also on other parts of the body. The markings are made either as a daily ritual, or on special occasions, and denote which particular lineage, or sampradaya the devotee belongs to. The different Vaishnava sampradayas each have their own distinctive style of tilak based on the siddhanta of their particular lineage. The general tilak pattern is of two or more vertical lines resembling the letter U, which commonly represents the foot of Vishnu.
