Ancient Indian Literature accords a special place to the Sun in the order of divinities, revering it as the creator and sustainer of the universe and ultimate course of all wealth. The Aditya Hrdayam (Hridayam), a short canto chapter of the Ramayana (by Adikavi Valmiki), offers obeisance to the Sun God. The secret of the eternal Stotram is conveyed by Sage Agastya to Lord Rama, who uses it to emerge victorious Over Ravana.
