Somappa Swamigal, a great Siddha Purushar, came around 1920 to Thirukkoodal Malai, when Mayandi Swamigal has well settled in Thirukkoodal Malai under the affectionate care of Thiru Irulappa Konar. His arrival was sensed by Mayandi Swamigal, and Mayandi Swamigal asked Irulappa Konar to take full care of Somappa Swamigal. Since then and upto the Maha Samadhi of Somappa Swamigal in 1968 Irulappa Konar and his descendents Sethumadhava Konar and Ramalinga Konar fed Somappa Swamigal with the same care and respect as they did for Mayandi Swamigal.
Many devotees including Muthuramalinga Thevar used to visit Somappa Swamigal in Thirukkoodal Malai. Somappa Swamigal used to call all the devotees by his own name “Somappa”. He has blessed many devotees with children, professional glory, and wealth.
When Mayandi Swamigal attained Mahasamadhi, Somappa Swamigal stood near the body and looked at the body intensively. At that time people noticed a smile at the lips of Mayandi Swamigal. Then Somappa Swamigal fled away towards the hill shouting “Somappa never dies”.
His Samadhi Koil is on the Thirukkoodal Malai at a height of around 50 feet. It is on the path way to Thandapani Temple at the top of the hill. His aradhana day is celebrated every year in the Tamil month of Aani by a large of his devotees.
