Govinda resides eternally in Vrndavana. In the spiritual world of Vrndavana the buildings are made of touchstone, the cows are known as surabhi cows, givers of abundant milk, and the trees are known as wish-fulfilling trees, for they yield whatever one desires. In Vrndavana Krsna herds the surabhi cows, and He is worshiped by hundreds and thousands of gopis, cowherd girls, who are all goddesses of fortune. When Krsna descends to the material world, this same Vrndavana descends with Him, just as an entourage accompanies an important personage. Because when Krsna comes His land also comes, Vrndavana is considered to exist beyond the material world. Therefore devotees take shelter of the Vrndavana in India, for it is considered to be a replica of the original Vrndavana. Although one may complain that no kalpa-vrksas, wish-fulfilling trees, exist there, when the Six Gosvamis were there, kalpa-vrksas were present. It is not that one can simply go to such a tree and make demands; one must first become a devotee. The Gosvamis would live under a tree for one night only, and the trees would satisfy all their desires. For the common man this may all seem very wonderful, but as one makes progress in devotional service, all this can be realized.
