Vibishana, brother of Ravana was presented with an Idol of Lord Perumal, by Rama, after he won over the Srilanka to rescue his wife Seetha. Vibishana wanted to take it back to Srilanka. Knowing this, Lord Vinayaka went in a disguise of a small boy. He tricked Vibishana and placed the idol in between a forest. He was then chased to the top of the hill and was hit hard on his head, making a small dent. Later, the idol was discovered and Srirangam temple was built. A good link between Saivam and Vaishnavism established through this story.
It is believed that Lord Ganesha is the obstruction remover, any devotee who comes and prays will have his problems removed and can restore a peaceful life. Devotees pray to lord Jurahareshwarar, for good health. It is believed that if you smear sandal to the idol, he restores your good health. After childbirth, people used to leave banana bunch as their token of thanks.
