As the one sun illumines this entire world, so the knower of the field, O Bhārata!, illumines the entire field.

The metaphor of the sun (ravi): just as one sun lights the whole world, one consciousness makes possible all experience of the field.

The kṣetrī — knower of the field — is not the individual ego but the universal consciousness that animates all fields. The ego is like a mirror reflecting the sun’s light.

This verse affirms the non-dual nature of consciousness: though appearing as many individual experiencers (kṣetra-jña), there is ultimately one Self.
