Vaideeswaran Koyil or Pullirukkuvelur enshrining Shiva as the divine physician, is also well known for its shrine to Mutthukumaaraswamy or Subramanyar. The tamil name Pullirukkuvelur arises from the legend that Jatayu (a bird), Irukku (Rig Veda), Vel (Skanda) and Oor (the sun) offered worship to Shiva here.

Legend has it that Murugar was blessed with his spear here. The legend holds at Sikkal and at Tirumayilai. Another legend has it that Shiva offered worship to Skanda here, hence the great significance attached to the Subramanyar shrine.

The images of Skanda (both the moolavar and the processional bronze image) are of great beauty.

The Mutthukumaaraswamy shrine is situated in the innermost prakaram. In front of the shrine is the sacrificial altar, the ashes from which are used to make the prasadam (along with the mud from the Angasanthana theertnam) Tiruchaandu Urundai which is believed to be a cure for many an ailment. This prasadam is distributed after being placed in the Ambal (Tayyalnaayaki) shrine.

Another prasadam offered here, which is also believed to be a cure for many ailments is the Nettirapidi Sandanam, which is sandal paste mixed wish saffron placed at the feet of Mutthukkumaaraswamy and then offered to devotees.

Several festivals are celebrated throughout the year in this temple. Two annual Bhramotsavams - one in Thai (for Mutthukkumaraswamy) and one in Panguni (Vaitheeswaran) are celebrated here. Skanda sashti is another of the major festivals celebrated here.

The Kartikai asterism each month attracts large crowds at the Mutthukumaraswamy shrine.
