Tavathiru Nachiappa Gnanadesika Swami is leading the Koviloor Aadheenam as its 12th Matadhipathi. He is a direct descendant of the Koviloor Andavar. He has been
acclaimed world over for his expertise in photography and printing technology. He was part of the Kalakshetra established by Smt. Rukmini Devi Arundable for nearly six decades. After taking over the running of the Math, his objective has been the spreading of 'Sanatana Dharma' all over the world; for this purpose he has been spending all the wealth he earned in his 'Poorvashrama' (life before taking 'Sanyas') and working with total commitment.

     As a beginning he established the Andavar Nursery School immediately after taking charge of the Math in 1995 which benefits the poor children of the locality. A few
months later came into being institutions for teaching Nadaswaram, Thirumurai, Vedasivagama, construction of temple chariots, computer, free Siddha medical centre; in these institutions food and lodging are offered free to the students.
