In this universe there are millions of planets, and there exist as many universes as mustard seeds in a mustard seed bag. There are innumerable universes coming out of the pores of Mahavishnu’s body when He exhales; and when He inhales, they all enter back into Him. And Mahavishnu is only a portion of Krishna.
And beyond this material world there is the spiritual world, full of innumerable, gigantic spiritual planets called Vaikunthas, which are all resting in the effulgence of Sri Krishna, who engages in divine pastimes in Goloka Vrindavana, the supreme and eternal home with transcendental delights.
The supreme abode of the Personality of Godhead, Krishna, is described in the Brahma-samhita as cintamani-dhama, a place where all desires are fulfilled. The supreme abode of Lord Krishna, known as Goloka Vrndavana, is full of palaces made of touchstone. There are also trees, called “desire trees,” that supply any type of eatable upon demand, and there are cows, known as surabhi cows, which supply a limitless supply of milk. In this abode, the Lord is served by hundreds of thousands of goddesses of fortune (Lakshmis), and He is called Govinda, the primal Lord and the cause of all causes.
Vedic literatures (Katha Upanisad 1.3.11) state that there is nothing superior to the abode of the Supreme Godhead, and that that abode is the ultimate destination (purushan na param kincit sa kastha parama gatih). When one attains to it, he never returns to the material world. Krishna’s supreme abode and Krishna Himself are nondifferent, being of the same quality. This Supreme abode of Lord Krishna, is shaped like the whorl of a lotus flower. Even when the Lord descends to any one of the mundane planets, He does so by manifesting His own abode as it is.
On this earth, Vrndavana, ninety miles southeast of Delhi, is a replica of that supreme Goloka Vrindavana located in the spiritual sky. When Krishna descended on this earth, He sported on that particular tract of land known as Vrindavana, comprising about eighty-four square miles in the district of Mathura, India.
