This stotra is given in the twenty fifth chapter of samba purana. This great hymn of 21 names of sun god was initiated by lord Surya (sun god) himself to sāmba by appearing in his dream.
Praising the sun god through this hymn, Sāmba got cured of all his diseases and illnesses and became pure.
Praying to sun god with this hymn can help us get cured completely of all kinds of diseases, illnesses, and ailments by the grace of sun god.
