It is stated in the Puranas: "Persons who attempt to visit the holy places of pilgrimage, like Vrndavana, Mathura or Dvaraka, 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 Krsna. As we have explained previously, in Vrndavana, Mathura and Dvaraka 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 Krsna consciousness and who therefore go to see the Deities of Visnu 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 Visnu with devotional consciousness. Then one can very easily get out of the miserable condition of material birth.
