The International Society for Krishna Consciousness now has its world center in Navadvipa, Mayapur. The managers of this center should see that twenty-four hours a day there is chanting of the holy names of the Hare Krsna maha-mantra, with the addition of haraye namah, krsna yadavaya namah, for this song was a favorite of Sri Caitanya Mahaprabhu's. But all such sankirtana must be preceded by the chanting of the holy names of the five tattvas-sri-krsna-caitanya prabhu-nityananda sri-advaita gadadhara srivasadi-gaura-bhakta-vrnda. We are already accustomed to chant these two mantras-sri-krsna-caitanya prabhu-nityananda sri-advaita gadadhara srivasadi-gaura-bhakta-vrnda and Hare Krsna, Hare Krsna, Krsna Krsna, Hare Hare Hare Rama, Hare Rama, Rama Rama, Hare Hare. Now, after these, the other two lines-namely, haraye namah, krsna yadavaya namah gopala govinda rama sri-madhusudana-should be added, especially in Mayapur. Chanting of these six lines should go on so perfectly well that no one there hears any vibration other than the chanting of the holy names of the Lord. That will make the center spiritually all-perfect.
