This material world, whole universe, they are brightened by the sunshine. Kṛṣṇa is so kind. Because you cannot see without sunshine, without light—this place is dark—therefore in daytime there is sunshine; at night there is moonshine. Everything is arranged there. And in the Brahma-saṁhitā it is described:
- yac-cakṣur eṣa savitā sakala-grahāṇāṁ
- rājā samasta-sura-mūrtir aśeṣa-tejāḥ
- yasyājñayā bhramati sambhṛta-kāla-cakro
- govindam ādi-puruṣaṁ tam ahaṁ bhajāmi
- (Bs 5.52)
Now this sun is described as the eye of all planets, yac-cakṣur eṣa sakala-grahāṇāṁ. Sakala means "All the planets." The eyes . . . real eye is the sun, because without sunshine we cannot see. In this planet or any planet you go, as soon as there is sunshine you can see; otherwise you cannot see. Therefore real eye is the sun. Yac-cakṣur eṣa savitā sakala-grahāṇāṁ. Rājā: he is the king, samasta-sura-mūrtir, of all the demigods. There in the sunshine, there is a president. As you have got a president here, similarly the sun planet there is president. His name is Vivasvān.
