The temple of Ettumanoorappan has a special sanctity and glorious history of its own. Owing to the potency and all prevading power of the “Aghora Moorthy” the Temple stands first among the pIaces of worships and pilgrimage in South India arid it attracts devotees not only from India but also from abroad.
Great Saint “Khara Prakasha” worshipped God ‘Paramasiva” to wash off his sins and prayed “Siva” to bless him so that he could install “Sivalinga’ for the betterment of humanity. Lord Siva appeared before him, blessed him and presented Lord’s own idoI. Saint Khara installed this Siva Linga facing West at Ettumanoor. This “Aghora Moorthy” is said to be grave in nature, Saint Khara left the place after he had installed the idol In the present position . For many years it remained quite unknown and this place became a dense forest.
The identity of this Sivalinga was then explored by a Harijan woman. Once she was collecting arrow roots with her sickle and struck a stone which at once began bleeding. Simultaneously her tool and basket were thrown off which fell at the Vadayar near Vikom and at Ettumanoor itself.
The lady then informed this matter to the authorities and thence the presence of divinity was publicized. A ridge is still visible on the Siva Linga believed to be the sickle marks.
At this stage an Astrological Survey was conducted by the local administration whence it was determined that this Sivalinga was brought to this place by a Saint together with other two SivaLingas. One of them was consecrated at Vaikom and another one at Kaduthuruhy enroute.
Unfortunately another Sage who visited this place later happened to be disrespected by the locals and he impricated that this place should remain unnoticed and abandoned. After thousands of years, Saint Vilwamangalathu Swamiyar revealed the divinity here and the temple was removated. This was further reconstructed by Pandya King Chanda Bhakaran in the present form around 1540 AD. A Brahmin house at Ettumanoor ‘Ettonnasseri illom” offered vast lands to the temple and in return became legatees to one-eighth of the temple offerings.
Many vedic names are associated with this temple and it is believed that Pandavas, Sage Vyasa and Religion Shri Adi Shaankaracharya, devotee of Lord Shiva composed his Soundarya Lahari here.
