divi sūryasahasrasya bhavedyugapadutthitā |yadi bhāḥ sadṛśī sā syādbhāsastasya mahātmanaḥ ||
If the light of a thousand suns were to rise all at once in the sky, that would be like the radiance of that great-souled being.
Explanation
Sanjaya is describing to the blind king Dhritarashtra the universal form (viśvarūpa) that Krishna shows Arjuna. He says that only the light of a thousand suns rising together in the sky would resemble its brilliance. The comparison is hypothetical ("if"), which signals that the vision goes beyond anything ordinary experience can match.
