Adithyahridayam

Adithyahridayam - A hymn associated with Aditya or the Sun God and was recited by the sage Agastya to Rama on the battlefield before fighting with Ravana. This historic hymn starts at the beginning of the duel between Rama and Ravana. Agastya teaches Rama, who is fatigued after the long battle with various warriors of Lanka, the procedure of worshiping the Sun god for strength to defeat the enemy. These verses belong to Yuddha Khanda (Book 6) Canto 107, in the Ramayana as composed by Valmiki.
