viśvarūpaṃ hariṇaṃ jātavedasaṃ parāyaṇaṃ jyotir ekaṃ tapantam /
sahasraraśmiḥ śatadhā vartamānaḥ prāṇaḥ prajānām udayaty eṣa sūryaḥ //

The enlightened realisers of Brahman knew, as their own soul, that sun that is viśvarūpam, possessed of all forms; hariṇam, full of rays; jātavedasam, endowed with enlightenment;footnote{The phrase may mean, "The knower of all that is born".} parāyaṇam, the resort of all lives; ekam jyotiḥ, the only one light, the eye, of all beings; tapantam, the radiator of heat. Who is that whom they knew? Eṣaḥ, this is; sūryaḥ, the sun; that udayati, rises;—the sun that is sahasraraśmiḥ, possessed of a thousand rays, śatadhā vartamānaḥ, that exists in a hundred (many) ways, in conformity with the difference of the creatures; and that is prāṇaḥ prajānām, the life of creatures.
