Hiding his rosary under his dhoti, he is reciting mantra supposed to draw sun energy on him.
"Let us chant the glories of the Sun god, whose beauty rivals that of a flower. I bow down to him, the greatly effulgent sun of Kasayapa who is the enemy of darkness, and destroyer of all sins.
He is the lord of the stars, planets and constellations and the origin of every thing in the universe, the resplendent among the splendid. Oh! God, appearing in twelve forms (in the shape of twelve months of the year) salutations to you."
This is a time of sending blessings towards all living creature in universe, a time for thanks.
