Tiruthanikai ranks prominent as the crown jewel of Lord Muruga. As its very name indicates, when we propitiate our Lord in this holy shrine, He blesses us with mental peace and bodily happiness. His righteous indignation towards the asuras for their cruelty is said to have been quelled and cooled at this place, which is, therefore, known as Shantipuri (Abode of Peace). As the prayers and desires of the devotees who worship our Lord Thanikeshan on this hill with unswerving faith and intense devotion are fulfilled in no time, this hill is also called Thanikachalam.
In Treta Yuga, Lord Rama, after putting an end to Ravana, worshipped Lord Siva at Rameshwaram, at whose request Rama came to Tiruthani and found perfect peace of mind by worshipping our Lord Subrahmanya here. In Dwapara Yuga, Arjuna got the blessings of our Lord here by offering prayers to Him on his way to the South for Teertha Yatra (pilgrimage to take sacred immersion). Lord Vishnu prayed to our Lord at this place and got back His powerful Chakra (sacred wheel), Shanku (sacred conch), which were forcibly seized from Him by Tarakasura, brother of Soorapadma.
Sage Agasthya worshipped Lord Muruga at Thanikai and was blessed with the rare divine gift of the ever-sweet peerless Tamil language, the beauty of which has been extolled by all the great saints and poets of Tamil Nadu.
It is said that Muruga stopped at many places en-route for a few moments for a quick rest as also to enjoy their natural beauty, only to find that Ganesha was already present before His arrival.
3. Swami Malai
Sage Bhrigu, before commencing arduous tapas, got the boon that anybody disturbing his mediation will forget all his knowledge. Such was the power of the penance that the sacred fire emanating from the head of the saint reached up to the heavens, and the frightened Devas surrendered to Lord Siva praying for his grace. The Lord extinguished the sacred fire by covering the saint’s head with His hand. With the saint’s penance thus disturbed the Lord became oblivious of all his knowledge and is said to have regained them by learning the Pranava mantra from Lord Muruga at this shrine.
