The tilak

The two Iyengar denominations, the Tenkalai and the Vadakalai, wear the namam with slightly altered designs. The namam for the adherents of the Tenkalai tradition includes a white bow that extends to the bridge of the nose, shaped like a Y. A red line runs down the middle of this design. The adherents of the Vadakalai tradition wear a similar white bow-shaped design shaped like a U, featured entirely upon the forehead. A red or sometimes yellow line runs down the middle of this design.

Priests serving in temples traditionally wear the Thiruman Srichurnam on 12 spots of their body (dvadasa pundram) according to the Samasrayanam.

The forms of the naamam are depicted in the gallery below.

The abbreviated form

The abbreviated namam is more commonly worn by Bhagavathars, Iyengars, as well as all denominations of Sri Vaishnavas, and Pandaris in daily life. It consists of a single thin, vertical red or yellow line worn in the middle of the forehead. This abbreviated namam has become commonplace in religious as well as secular events.
