It is understood from scriptures like the Brahma-saṁhitā that in the spiritual abode of the Lord the houses are made of touchstone and the trees are all desire trees. There the Lord is accustomed to tending thousands and thousands of kāmadhenus (cows able to supply unlimited quantities of milk). And all the houses, trees, and cows are qualitatively nondifferent from the Lord. The Lord and His paraphernalia in the spiritual abode are one and the same in quality, although there are differences for the pleasure of the Lord. In the material world also we have various paraphernalia for our pleasures in life, but because all this paraphernalia is made of matter, it is all destructible at the end. In the spiritual sky there are the very same varieties of pleasure, but they are all meant for the Lord. There the Lord alone is the supreme enjoyer and beneficiary, and all others are enjoyed by the Lord. The Lord is served there by all kinds of servitors, and both the master and the servitors are of the same quality. This spiritual variegatedness is displayed by the Lord when He descends at Vṛndāvana, and we may know that the Lord descends with His personal staff of cows, cowherd boys, and cowherd maidens, all of whom are but spiritual expansions of the Lord Himself for His own pleasures. Thus when called by the Lord the cows were overwhelmed by joyous affection, just as the mother’s breast overflows with milk when the child cries for it.
