Mahabharata legends
Legend has it that the Pandava princes, after crowning Parikshit left on a pilgrimage of India, and in Kerala, each of these brothers installed Vishnu on the banks of the Pampa and nearby places and offered worship. (Chengannur,Thrichittattu - Yuddhishtra, Tiruppuliyur - Bheema, Aranmula - Arjuna, Tiruvamundur - Nakula and Tirukkadittaanam - Sahadeva). It is said that Arjuna built this temple at Nilackal near Sabarimalai. and the image was brought here in a raft made of six pieces of bamboo to this site, and hence the name Aranmula (six pieces of bamboo). Legend has it that Arjuna built this temple, to expiate for the sin of having killed Karna on the battlefield, against the dharma of killing an unarmed enemy. It is also believed that Vishnu (here) revealed the knowledge of creation to Bhrama, from whom the Madhukaitapa demons stole the Vedas. There is yet another legend associated with Parthasarathy here. On the ninth day of the battle of Kurukshetra, the Kauravas reigned supreme under the leadership of Bheeshma, when Krishna motivated Arjuna to take initiative and vanquish his foe. Upon his hesitating to do so, Krishna jumped down in rage, and took up his discus; seeing this sight Bheeshma surrendered to him and Arjuna beseeched him not to kill Bheeshma, as it would bave been against Krishna's vow to take up arms in his battle. It is believed that it is this image of Krishna that is enshrined here, with a discus.
