Mainaka Mountain is situated in the southern sea that lies between india and Lanka. Mainaka is said to be the son of Himalaya. In early days, it had wings and could fly freely in the sky. Indra, the king of Gods, caused his wings to be clipped. With the help of Vayu (the God of Wind) Mainaka reached the southern sea and sank into its depths. Since then it has dwelt underwater.
When Hanuman was searching for Sita, traveling through the air the ocean asked Mainaka to rise up and allow Hanuman to rest a while. After all, it was Vayu, Hanuman’s father that had helped Mainaka find his place in the southern sea. On his bidding, Mainaka rose up and requested Hanuman to rest on him for a while. But Hanuman said, “I am on a mission I have undertaken for Shri Rama, I will not rest unless it is completed.”
Disappointed, Mainaka sank back into the depths of the ocean again.
