It is stated in the Purāṇas, "Persons who attempt to visit the holy places of pilgrimage, like Vṛndāvana, Mathurā or Dvārakā, are actually glorified. By such traveling activities, they can pass over the desert of material existence."
In the Hari-bhakti-sudhodaya there is a statement about the benefit of visiting the temples of Lord Kṛṣṇa. As we have explained previously, in Vṛndāvana, Mathurā and Dvārakā the system is that all the devotees take advantage of visiting various temples situated in those holy places. It is stated in the Hari-bhakti-sudhodaya, "Persons who are impelled by pure devotional service in Kṛṣṇa consciousness and who therefore go to see the Deities of Viṣṇu in the temple will surely get relief from entering again into the prison house of a mother's womb." The conditioned soul forgets the trouble of living within the mother's womb during birth, but it is a very painful and terrible experience. In order to make an escape from this material condition, one is advised to visit a temple of Viṣṇu with devotional consciousness. Then one can very easily get out of the miserable condition of material birth.
