Lord Mahavishnu in the disguise of Mohini, went to the Asuras and got back the Amrutham and restored it to the Devas. When Lord Shiva, went to see Lord Mahavishnu who was in the guise of a Mohini succumbed to her beauty and out of their union, was born a child, who was name Dharmasastha. Dharmasastha grew at Kailasham. Lord Shiva, answered Rajasekara's prayer and ordered Dharmasastha to ake the avathar of Ayyappan . On the day King Rajasekara went for hunting in the forest, Ayyappan took the form of a baby with a golden chain and bell around his neck and placed himself near the Pamba river.

King Rajasekara went for hunting in the forest adjoining the banks of River Pampa, along with his men. He started hunting courageously in the dense forest which was a sanctuary for many wild animals. After that hunting was over, King Rajasekara advised his men to take rest and sat there entertaining himself with the sight of the natural greenish beauty and the waterfalls, of the forest.

At that time, he heard a child crying from somewhere in the forest. Surprised, he went round and reached the banks of River Pampa. There he saw a beautiful and divine child (i.e. Ayyappa) kicking its legs and crying out, and was in a dilemma whether to take the child to the Palace or leave it there itself.
