Kalika purana tells that, Vishnu in the form of Hyagreeva kílled the fever demon, Jwarasura at Munikuta parvata and took a recovery bath at Apunarbhava. As the name suggests, the one who takes bath in this pond will not have second birth even though he enjoys worldly things.
Yogini Tantra tells that king Indra dyumna saw a big tree in the dream floating by the sea shore. The next day morning he really saw that tree and with an axe he cut it in to seven pieces. Two of them were brought to Kama rupa and the idols of Hayagreeva(Who kílled the demon Hayagreeva and saved Vedas) and Madhava(Matsyavatara) are sculptured from them.
