Ayyappan Songs in Tamil. Ayyappan also known as Dharmasasta, Maṇikanṭhan or Sasta, is a Hindu deity who is the son of Harihara, fused with both Shiva and Vishnu. He is generally depicted in a yogic posture, wearing a jewel around his neck, hence named Maṇikaṇṭhan, which literally means "person with gem around the neck".
