The origin of Vrichika Ashtami festival is an interesting one and the legend has it that once demon Khara on the advice of  Malayavan did  prolonged penance and meditation on God Shiva at Chidambaram to get liberation/ salvation.  At last, God Shiva granted him three lingas out of him and asked him to worship them for moksha. Upon his return from the Himalayas when he was passing thru the present site now part of Vaikom, he took a break from fatigue and rested for a while.  When resuming  his journey  demon Khara was unable to move the lingam and at the same time he heard divine  heavenly voice (asareeri). "I shall remain here giving Moksha (salvation) to whoever takes refuge in Me!"  Pleased as he was,  he handed over the lingams to sage Vyaghrapada who tailed him invisibly without his knowledge.   

The famous Vaikkathashtami festival on the day of Vrichika Ashtami  owes its origin on the day God Shiva and his consort Parvati appeared before  sage Vyaghrapada and said,   "This place shall be known as Vyaghrapadapurma" Years later  great Parasurama saw the lingams partly submerged in the waters and immediately  understood its divinity.  He made special efforts and consecrated the lingas  with relevant mantras. Subsequently, to continue the traditions and customs, he entrusted the temple to a devout  Brahmin family. Since then the puja rituals  at the vaikom temple have been going on as per norms  laid down by Parasurama.
