During the Arudra star in the Tamil month of Margazhi (Dec 15 – Jan 15) is believed to be the time when Lord Shiva’s energy is very close to the earth; hence it has been given the importance of being His birthday. Lord Shiva is worshipped as Nataraja in this month which is also observed as Lord Nataraja Urchavam at Arunachaleswarar Temple.
The month of Margazhi is also known as the ‘Twilight’ in Heaven (the time that the sun is in Sagittarius), and is considered the most appropriate time in which the Gods can rest and rejuvenate. This year, 2012, Arudra Darshan was observed today December 28.
Lord Shiva is worshipped in the cosmic dance form as Lord Nataraja, and the full moon night of Margazhi is also the longest night of the year. After this date, days get longer and nights get shorter.

The cosmic dance of Lord Shiva represents five activities – Creation, Protection, Destruction, Embodiment and Release. In essence, it represents the continuous cycle of creation and destruction.
"Modern physics has shown that the rhythm of creation and destruction is not only manifest in the turn of the seasons and in the birth and death of all living creatures, but is also the very essence of inorganic matter...For the modern physicists, Shiva's dance is the dance of subatomic matter . . . Hundreds of years ago, Indian artists created visual images of dancing Shivas in a beautiful series of bronzes. In our time, physicists have used the most advanced technology to portray the patterns of the cosmic dance. The metaphor of the cosmic dance thus unifies ancient mythology, religious art and modern physics."
