The importance of the temple lies in it being a sacred pilgrim spot for the Hindus having both Shiva and Vishnu's shrines present. Many Hindus also believe that this place was a jasmine forest long, long ago and because of the beautiful smell of jasmine, the god Kamadhenu, the wish fulfilling divine cow, dwells in this temple. Thus the people come from far and wide to seek his blessings and get their wishes and desires fulfilled.

Though the temple is said to be a Saiva temple, in reality, it is dedicated to the mighty Lord Shiva. But the main deity here, however is Lord Singaravelavar. According to mythology, Rishi Vasishta had created a Shivalingam out of butter which was made from the divine cow, Kamadhenu's milk. After performing the puja, he saw that the Shivalingam was stuck at the place and could not be shifted. This gave the place its name' Sikkal'. It is believed that Rishi Vashishta and Rishi Viswamitra have both worshipped the lord in this temple.

Everyday there are six services offered to Lord Murugan. Marriages too take place in the temple in the Kalyana Mandapam. A major annual festival is Brahmotsavam which is celebrated in the Tamil month called Chittirai. Another festival that draws a huge number of devotees and tourist is the Skanda Shashti Utsavam celebrated in a grand way in the Tamil month of Arpasi. It is held in honour of Singaravelavar. It is said that during Skanda Shashti, the Lord would receive his spear or Vel as they call it, from his mother a day before Surasamharam to slay a demon called Surapadman. The mark of the receiving of the Vel would be the miraculous sweating of Murugan's idol. This legendary myth draws a lot of curious visitors to Sikkal Singaravelavar Murugan Temple.
