Golden Monitor Lizard (Makaral / Udumbu) Legend
According to the Thondaimandala Puranam, an early Chola monarch (identified in inscriptions with Rajendra Chola I) was hunting in the dense jackfruit forests along the Cheyyaru River. The king spotted a radiant golden monitor lizard (Udumbu / Makaral) and gave chase. The creature darted into a thicket of jackfruit trees and disappeared into a large anthill.
When the king commanded his hunters to dig open the anthill with iron crowbars, the iron tip struck a hard stone object, and blood began to flow from the earth. Terrified, the king cleared the soil with his own hands and discovered a self-born Shiva Lingam shaped like the tail of a monitor lizard, bearing a fresh scar on its crown. Lord Shiva manifested before the king, accepted his repentance, and healed the wound. The king constructed a magnificent granite temple over the site and named the sthalam Thirumakaral (Makaral = Monitor Lizard / Iguana), and the deity Sri Makaraleswarar. The Lingam's crown still retains the unique tail-shaped curve.
Sage Agastya's Leg Healing Legend
Sage Agastya suffered from severe joint pains and leg paralysis after traveling south from Mount Kailash. On divine guidance, Sage Agastya arrived at Thirumakaral, bathed in the Cheyyaru River (Agastya Theertham), and worshipped Lord Makaraleswarar with fresh jackfruit leaves and bilva.
Lord Shiva appeared, touched Agastya's legs, and restored complete mobility and strength. Devotees suffering from arthritis, rheumatism, joint disorders, and leg injuries offer oil lamps and oil abhishekam to Lord Makaraleswarar, believing that worshipping here cures all physical limb ailments.
Saint Thirugnanasambandar's Tevaram Miracle
Saint Thirugnanasambandar visited Thirumakaral in the 7th Century CE and composed a 10-verse Tamil Tevaram decad starting with "Neeru Vangupul" (நீறு வாங்குபுல்). Sambandar proclaimed that anyone who sings these 10 hymns with devotion shall be completely cured of leg pains, joint diseases, and karmic rebirths.
