"The special qualification of the pure devotee is that he is always thinking of Krsna without considering the time or place. There should be no impediments. He should be able to carry out his service anywhere and at any time. Some say that the devotee should remain in holy places like Vrndavana or some holy town where the Lord lived, but a pure devotee can live anywhere and create the atmosphere of Vrndavana by his devotional service. It was Sri Advaita who told Lord Caitanya, 'Wherever You are, O Lord -- there is Vrndavana.'"
(Bhagavad-gita As It Is, 8.14, Purport)
