The disappearance of the sun that Krishna represents can be explained as follows. Uddhava perceives the pain of Vidura, and that is why he first and foremost wants to sympathize with him by saying that after sunset, all beings are plunged into darkness. The entire universe now submerged in the darkness of affliction, neither Vidura nor Uddhava can experience joy. Uddhava felt just as saddened as Vidura, and found nothing to say about the well-being of his relatives.
Krishna's comparison with the sun is quite fitting. As soon as the sun sets, the darkness immediately appears. But the darkness that envelops men does not touch the sun, whether at sunrise or sunset. In this, the appearance and disappearance of Sri Krsna are similar to those of the sun. The Lord appears and disappears in innumerable universes, and when He is present in a particular universe, it is immersed in the spiritual light, while another, which He has just left, is again immersed in the darkness. However, these entertainments are going on forever. Indeed, the Lord is always present in one or the other of the innumerable universes (galaxies), just as the sun is always going through one of the two hemispheres, sometimes to the East, sometimes to the West.
Just as the sun appears in the morning and rises gradually to the meridian and then goes to bed even as it rises in another hemisphere, the disappearance of Krishna in one universe corresponds to the beginning of his many amusements in another. To be more precise, as soon as entertainment ends on earth, it begins to manifest itself elsewhere. It is in this way that his eternal diversions continue unabated. We know that the sun rises once in twenty-four hours; similarly, Krishna's amusements become visible in a once-given universe of Brahma; and this day lasts four billion three hundred and twenty million (4,320,000,000) solar years. But wherever the Lord finds himself, all his wonderful diversions unfold as revealed by revealed scriptures at regular intervals.
As the sun sets, the snakes gain strength, the thieves feel more courage and the specters become active, the lotuses wither and the cakravakis birds lament. Likewise, when Lord Krishna disappears, atheists feel enlivened, but holy beings grieve.
This universe (the Milky Way) with all its planets is plunged into desolation. But even more unfortunate are the members of the Yadu dynasty, the family of the Lord, who failed to recognize the Supreme Personality of Godhead.
Uddhava mourns the misfortune of those who, in this world, failed to recognize Lord Krishna, while He was in their presence, and all his divine, spiritual and absolute attributes were manifested before their eyes. From the moment of his advent, He displayed His divine powers, as the Supreme Lord, through the six excellences of wealth, strength, fame, beauty, knowledge, and renunciation; and yet fools did not know how to recognize in Him the Supreme Being. Fools, having had no close contact with the Lord, thought that he was simply an extraordinary historical figure, but even more unfortunate than they were the members of the Lord's family, the members of
