Srila Bhaktisiddhanta Sarasvati Thakura elucidates this complicated explanation of Krsna's pastimes. Krsna's pastimes are always present in the material world in one of the many universes. These pastimes appear in the universes one after the other, just as the sun moves across the sky and measures the time. Krsna's appearance may be manifest in this universe at one moment, and immediately after His birth, this pastime is manifest in the next universe. After His killing of Putana is manifest in this universe, it is next manifest in another universe. Thus all the pastimes of Krsna are eternally existing both in the original Goloka Vrndavana planet and in the material universes. The 125 years calculated in our solar system to be Krsna's lifetime equal one moment for Krsna. One moment these pastimes are manifest in one universe, and the next moment they are manifest in the next universe. There are unlimited universes, and Krsna's pastimes are manifest one moment after the other in all of them. This rotation is explained through the example of the sun's moving across the sky. Krsna appears and disappears in innumerable universes, just as the sun appears and disappears during the day. Although the sun appears to rise and set, it is continuously shining somewhere on the earth. Although Krsna's pastimes seem to appear and disappear, they are continuously existing in one brahmanda (universe) or another. Thus all of Krsna's lilas are present simultaneously throughout the innumerable universes. By our limited senses we cannot appreciate this; therefore Krsna's eternal pastimes are very difficult for us to understand. One should try to understand how they are taking place by understanding the allegory of the sun. Although the Lord is appearing constantly in the material universes, His pastimes are eternally present in the original Goloka Vrndavana. Therefore these pastimes are called nitya-lila (eternally present pastimes). Because we cannot see what is going on in other universes, it is a little difficult for us to understand how Krsna is eternally manifesting His pastimes. There are fourteen Manus in one day of Brahma, and this time calculation is also taking place in other universes. Krsna's pastimes are manifest before fourteen Manus expire. Although it is a little difficult to understand the eternal pastimes of Krsna in this way, we must accept the verdict of Vedic literatures.
