Materialists consider Vṛndāvana-dhāma an unclean city because there are many monkeys and dogs there, and along the bank of the Yamunā there is refuse. Some time ago, a materialistic man asked me, “Why are you living in Vṛndāvana? Why have you selected such a dirty place to live after retiring?” Such a person cannot understand that Vṛndāvana-dhāma is always a representation of the original Vṛndāvana-dhāma. Consequently Vṛndāvana-dhāma is as worshipable as Lord Kṛṣṇa. Ārādhyo bhagavān vrajeśa-tanayastad-dhāma vṛndāvanam: according to Śrī Caitanya Mahāprabhu’s philosophy, Lord Śrī Kṛṣṇa and His abode, Vṛndāvana, are equally worshipable. Sometimes materialistic people who have no spiritual understanding go to Vṛndāvana as tourists. One who goes to Vṛndāvana with such materialistic vision cannot derive any spiritual benefit.
