Arunachala has always been renowned as the bestower of liberation, the destroyer of the ego, the remover of the false notion 'I am the body' - as the jnana-Guru par excellence.
When Brahma and Vishnu began to quarrel, being deluded by pride and egoism, Lord Arunachala Siva appeared before them in the form of a column of fire, thereby vanquishing their egoism and teaching them true knowledge. When Sakti, Goddess Parvati, wished to attain a state in which she could do no wrong, Lord Siva sent her to Arunachala, where she merged and became one with him. Thus, even to Brahma and Vishnu, Arunachala was Guru, and to Parvati it was the place where she lost her separate individuality.
Throughout the ages saints and sages have sung verses in Sanskrit, Tamil and other Indian languages extolling the unique power of Arunachala to root out the ego and to bestow Self-knowledge. All the four great Saiva sages of Tamil Nadu, Manikkavachagar, Sundaramurti, Appar and Jnanasambandhar, have sung in praise of Arunachala. In one verse often pointed out by Sri Bhagavan, Jnanasambandhar described this hill as being jnana-tiral, a dense mass of jnana. And Sundaramurti, singing in Tiruvanaikka, remembers Arunachala and sings, 'O Annamalai, you can be known only to those who give up the attachment to the body'.
