Today is Maha Shivratri — Great night of Shiva. Shiva (the auspicious one) is known by many names — Mahadeva or Mahesh (the great god), Bholenath (the simple god since he is an ascetic), Parameshwara (the supreme god), and Nataraja (the king of dance). I am partial to Shiva as the Nataraj. He dances the Tandava, the dance of destruction and creation.
