The residents of Vṛndāvana and Mathurā are devotees of Kṛṣṇa in parental affection, and their feelings always conflict with the opinions of smārta-brāhmaṇas. Devotees who worship Kṛṣṇa in opulence cannot understand the parental devotional feelings of the residents of Mathurā and Vṛndāvana, who follow the path of spontaneous love. Devotees on the platform of vidhi-mārga (regulative devotional principles) may misunderstand the activities of those on the platform of rāga-mārga (devotional service in spontaneous love).
In his Amṛta-pravāha-bhāṣya, Śrīla Bhaktivinoda Ṭhākura advises that one avoid remaining in Vṛndāvana for a very long time. As the saying goes, “Familiarity breeds contempt.” If one stays in Vṛndāvana for many days, he may fail to maintain proper respect for its inhabitants. Therefore those who have not attained the stage of spontaneous love for Kṛṣṇa should not live in Vṛndāvana very long. It is better for them to make short visits.
