The Avataras

Lord Krishna remains in this Universe for 125 years only, but all the Pastimes of that period are exhibited in each and every Universe, including His Appearance, His Boyhood Pastimes, His Youth, and His manifestation of later Pastimes—until the last at Dwarka. All those Pastimes are present in one or another of the myriad  Brahmandas , at any given time. Therefore the Pastimes are called eternal. In other words, as the Sun is eternally existing and we can see it rise and set due to our different planetary position, similarly, the Lord's Pastimes are going on, but only at certain intervals can we see the Pastimes of Krishna in this particular Universe. As described above, His Abode is the Supreme Planet known as  Goloka Vrindaban  and, being Absolute, His Name, Fame, everything is equal to Krishna. And, by the will of Krishna, the same  Goloka Vrindaban  is manifested in this Universe and other Universes also.
Therefore, although the Lord is always in His Supreme Abode,  Goloka Vrindaban , by His Supreme will the activities there are also manifested in the innumerable Universes; and when He appears, He appears in those particular places. And in every manifestation of Krishna the six opulences are displayed.
