Aditya Hrudayam is a Hindu devotional hymn dedicated to Āditya or Sūrya (the Sun God) found in the Yuddha Kānda (6.105) of Vālmīki’s Rāmāyana.

This is one of the best slokas in the lineage of worship of Lord Sūrya. It was recited by the sage Agastya to Rāma on the battlefield before fighting the demon king Rāvaṇa.

In it, Agastya teaches Rāma, who is fatigued after the long battle with various warriors of Laṅkā, the procedure of worshiping Āditya for strength to defeat the enemy.
