Sri Mallikarjuna Swamy is one of the twelve Jyothirlingas of Lord Shiva situated at Srisailam in Andhra Pradesh state, India. It is one of the 275 Paadal Petra Sthalams.
As per Shiv Mahapuran, once Brahma (the Hindu God of creation) and Vishnu (the Hindu God of saving) had an argument in terms of supremacy of creation. To test them, Shiva pierced the three worlds as a huge endless pillar of light, the jyotirlinga. Vishnu and Brahma split their ways to downwards and upwards respectively to find the end of the light in either directions. Brahma lied that he found out the end, while Vishnu conceded his defeat. Shiva appeared as a second pillar of light and cursed Brahma that he would have no place in ceremonies while Vishnu would be worshipped till the end of eternity. The jyotirlinga is the supreme partless reality, out of which Shiva partly appears. The jyothirlinga shrines, thus are places where Shiva appeared as a fiery column of light. Originally there were believed to be 64 jyothirlingas while 12 of them are considered to be very auspicious and holy. Each of the twelve jyothirlinga sites take the name of the presiding deity - each considered different manifestation of Shiva. At all these sites, the primary image is lingam representing the beginningless and endless Stambha pillar, symbolizing the infinite nature of Shiva. The twelve jyothirlinga are Somnath in Gujarat, Mallikarjuna at Srisailam in Andra Pradesh, Mahakaleswar at Ujjain in Madhya Pradesh, Omkareshwar in Madhya Pradesh, Kedarnath in Himalayas, Bhimashankar in Maharastra, Viswanath at Varanasi in Uttar Pradesh, Triambakeshwar in Maharastra, Vaidyanath at Deogarh in Jharkand, Nageswar at Dwarka in Gujarat, Rameshwar at Rameswaram in Tamil Nadu and Grishneshwar at Aurangabad in Maharastra.
When Shiva and Parvathi decided to find suitable brides for their sons, Ganesha and kaarthikeya argued as to who is to get wedded first. Lord Shiva bade that the one who goes round the World in Pradakshinam could get married first. By the time Lord Muruga could go round the world on his vahana, Lord Ganesha went round his parents 7 times (for according to Sastras, going in pradakshinam round one's parents is equivalent to going once round the world (Boopradakshinam). Lord Siva got Siddhi & Buddhi, the daughtersof Viswaroopan married to Lord Ganesha. Muruga on his return was enraged and went away to stay alone on Mount Kravunja in the name of Kumarabrahmachari. On seeing his father coming over to pacify him, he tried to move to another place, but on the request of the Devas, stayed close by. The place where Lord Siva and Parvathi stayed came to be known as Sri Sailam. Lord Siva visits Lord Muruga on Amavasai day & Parvathi Devi on Pournami. The temple is situated facing East. The centre mandapam has several pillars, with a huge idol of Nadikeswarar.
Mahashivratri is the main festival celebrated at Srisailam Mallikarjuna Swamy temple.
