[![enter image description here][1]][1] Thiruman
Thiruman is obtained from medium grade metamorphic rock. It is defined by having more than 50% platy and elongated minerals. It is found mainly in Melkote, Karnataka. Pundraka
Pundraka -(Urdhva pundra in Sanskrit), (Thiruman, or Thirunamam in Tamil) - ritual mark, means holy mud, is applied on the foreheads of devotees of Sri Narayana, and Lord Vishnu himself wears it on His forehead. Devotees
Devotees apply it as a mark of respect to Lord Vishnu, denoting they are holding His Lotus Feet on their forehead. The two white lines represent the feet of the Lord, and the red line represents Lakshmi Thaayar who is ever present with Him. According to other sources, the left line represent Lord Brahma, the right line Lord Siva and the middle portion is where Lord Narayana dwells with Mother Lakshmi. The meaning of Him wearing it is to show the Bhaktha that the protection to him is from all possible direction, if he surrenders to the Lord. Each thiruman placed on the body represents a different name of Sriman Narayana:
