What is OORDHWAPUNDRA (Namam on the forehead)?

Literally the word means a religious mark (Pundra) which is worn upright (oordhawa). In common parlance it is called Namam. The Indian tradition has always insisted upon its followers to wear namam appropriate to their faith on their bodies especially on their forehead. One such namam is Oordhwapundra. Its significance is that it dispels the darkness of ignorance and reduces sins to ashes.
