Vrndavana is actually experienced as it is by persons who have stopped trying to derive pleasure from material enjoyment. "When will my mind become cleansed of all hankering for material enjoyment so I will be able to see Vrndavana?" one great devotee asks. The more Krsna conscious we become and the more we advance, the more everything is revealed as spiritual.
