X, 121, 1] 'Hiranyagarbha came first into existence,' for that golden child did come first into existence;--'born he was the one lord of being;' for he indeed was born as the one lord of all this being;--'he upholdeth this earth and the sky,' for he (the sun) does uphold both the sky and the earth;--'to the god Ka let us do homage by offering!' Ka (Who?) is Pragâpati: thus, 'let us do homage to Him by offering!'
