Tripundra (Sanskrit: "three marks") or பட்டை / Pattai in Tamil is a saivite tilaka. 'Tripundra' refers to the three mukti. tri means three, pundra means one which is released. There are three horizontal lines of vibhuti (holy ash) on the brow, often with a dot (bindu) as the third eye. The three lines represent the soul's three bonds: anava, karma, and maya.
