Of Lord Murugan’s six Padaiveedus, Tirutanikai ranks prominent as the crown jewel of our Lord.
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 Tanikesan on this hill with unserving faith and intense devotion are fulfilled in no time, this hill is also called Chanikasalam.
When Lord Murugan came to this hill after wedding Goddess Valli at Vallimalai, She implored Him to enlighten Her on the importance and greatness of this hill. In reply, our Lord said that if one worshipped Him with heart and soul for five consecutive days in this hill temple, that person would be blessed with all that is best in this life and hereafter.
In Treta Yuga, Lord Rama, after putting an end to Ravana, worshipped Lord Siva at Rameswaram, at whose request Rama came to Tiruttani and found perfect peace of mind by worshipping our Lord Subrahmanya here. In Dwapara Yuga, Arjuna got the blessings of Lord Murugan 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 Cakra (sacred wheel), Shanku (sacred conch), which were forcibly seized from Him by Tarakasura, brother of Soorapadma.
Lord Brahma propitiated Lord Murugan here at the holy spring (by the sides of the steps to the shrine) known as Brahmasonai after his imprisonment by Lord Murugan for his failure to explain the Pranava (‘Om’ mantra) and got back his creative function of which he was deprived by Lord Murugan due to his egotistic impudence in neglecting to worship Lord Subrahmanya on his way to Mount Kailasa to worship Lord Siva.
Lord Indra planted and reared in the pool known as Indrasonai adjoining this hill temple the rare plant known as Karunkuvalai, which gave three flowers a day and worshipped our Lord thrice daily with these flowers and , thus, got back the precious wealth of Deva Loka such as Sanghaneeti, Padmaneeti, Chintamani, etc seized by the asura titan.
Nanda Devi worshipped our Lord here on the bank of the Nandi River and got His peerless initiation to realize the unique relationship between the soul (jeevatma) and God (Paramatma), which is the quintessence of Saiva Siddhanta philosophy, the choicest product of the Dravidian intellect according the pioneering dravidologist Dr. G.V. Pope.
On worshipping our Lord at Thanikai, the king of snakes Vasuki got his bodily wounds healed, which had been caused during the churning process in the Milky Ocean to secure the Amrita (nectar of immortality) by the devas and asuras when the Mantotra Mountain was used as the churning base and the snake king Vasuki as the rope. Sage Agasthyar Muni (of Potikai Hill) worshipped our Lord at Tanikai when he 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.
