Tato yuddha pari srantam Samare Cintaya Sthitami
Ravanam Cagrato drustva yuddhaya Samupasthitam
Daivataisca Samagamya drastu = mabhyagatoranam|
Upagamyabra Vidrama magastyo bhagavanrsih
The Great Agastya, saw Lord Rama crestfallen in battle. In order to save
from His depression, the sage adviced this ” Song of the Inner Sun”
Rama Rama Mahabaho srunu guhyam Sanatanam
Yena Sarva Nareehnvatsa Samare Vijayisyasi
This is the Secret of all secrets
By which you can win over your enemies
Those who have worshipped the Inner Sun

Aditya Hrudayam punyam Sarva satru Vinasanam
Jayavaham Japet Nityam Akshyayyam paramam sivam
