Tiru-Seingyalur is the birth place of Chandesa Nayanar, the first and foremost of the 63 Nayanmars. It was here a divine soul named Visarasarmar was born to the pious couple Yechaththan and Pavithrai. From a tender age, Visarasarmar immersed himself in the profound wisdom of the Vedha Agamas, mastering their esoteric teachings and cultivating a deep appreciation for the sacred arts. One fateful day, as he frolicked with his fellow young scholars, all of whom were well-versed in Vedic knowledge, Visarasarmar found himself in a pasture where cow-herds tended to their gentle bovine charges. There, he witnessed a distressing scene - a cow, in a moment of agitation, attempted to strike the herd with its horns, only to be beaten by the herdsman in retaliation. Moved by compassion, Visarasarmar gently admonished the herdsman for his harsh treatment of the animal. With the blessings of his learned companions, he took upon himself the noble task of herding the cows, showering them with love and care. Under his tender stewardship, the cows flourished, their udders brimming with an abundance of milk. Inspired by this bounty, Visarasarmar's heart swelled with the desire to offer this precious liquid in worship to Lord Shiva. By the banks of the river Manni, beneath the sheltering canopy of an Aththi tree, he crafted a Shiva Linga from the river's silken sands, anointing it reverently with the milk of the cows he so lovingly tended. Yet, not all understood the depth of his devotion. A misguided individual, witnessing this sacred act, hastened to the cow owners with a tale of wasteful indulgence, accusing Visarasarmar of squandering the precious milk. The owners, perturbed by this report, summoned Yechaththan, Visarasarmar's father, urging him to reprimand his son. The following day, Yechaththan trailed his son as he led the cows to pasture, his heart heavy with the weight of the townspeople's words. There, he beheld Visarasarmar's act of devotion, the milk cascading over the sand-crafted Linga in a sacred offering. Enraged, Yechaththan raised his staff, raining blows upon his son's absorbed form. Yet Visarasarmar, lost in the rapture of his Shiva puja, remained oblivious to the physical onslaught, his mind and body wholly surrendered to the divine. This only served to further inflame Yechaththan's anger, and in a moment of blind fury, he kicked the Shiva Linga, an act of grave Shiva 'Aparatham'. Visarasarmar, though cognizant of his father's identity, recognized the gravity of this transgression. With unwavering resolve, he cast the staff before him, which miraculously transformed into an axe, severing Yechaththan's leg. Undeterred by this shocking turn of events, Visarasarmar remained steadfast in his devotion, completing his Shiva puja with single-minded focus. Lord Shiva, moved by this display of unwavering dedication, manifested before him, enfolding Visarasarmar in a divine embrace. He declared himself the young devotee's father, bestowing upon him the exalted title of Chandesa, proclaiming that all that was His now belonged to Visarasarmar. In a gesture of ultimate grace, Lord Shiva removed the garland of flowers from his own braided hair, placing it upon Visarasarmar as a symbol of his elevated status. Thus, Visarasarmar became known as Chandesa Nayanar, a beacon of devotion and a leader among Lord Shiva's followers. Tiru-Appadi, the place where Visarasarmar worshipped the Shiva Linga and attained 'Mukthi' is near by. Of all the 63 Nayanmars, Chandeshwarar Nayanar is the only one who has the suffix 'Eeswarar' attached to his name.
