Wherever he (the devotee) lives, he converts that place into Vrndavana and Navadvipa. This means that materialism cannot touch him. This is the secret of success for one advancing in Krsna consciousness
Śrī Caitanya Mahāprabhu further advised the brāhmaṇa Kūrma, "If you follow this instruction, your materialistic life at home will not obstruct your spiritual advancement. Indeed, if you follow these regulative principles, we will again meet here, or, rather, you will never lose My company."
This is an opportunity for everyone. If one simply follows the instructions of Śrī Caitanya Mahāprabhu, under the guidance of His representative, and chants the Hare Kṛṣṇa mantra, teaching everyone as far as possible the same principle, the contamination of the materialistic way of life will not even touch him. It does not matter whether one lives in a holy place like Vṛndāvana, Navadvīpa or Jagannātha Purī or in the midst of European cities, where the materialistic way of life is very prominent. If a devotee follows the instructions of Śrī Caitanya Mahāprabhu, he lives in the company of the Lord. Wherever he lives, he converts that place into Vṛndāvana and Navadvīpa. This means that materialism cannot touch him. This is the secret of success for one advancing in Kṛṣṇa consciousness.
