Srila Prabhupada invited devotees from all over the world to come to Mayapur and Sri Vrindavan dham to associate with one another and to absorb the infinitely merciful environment of bhakti that permeated this holy place and to utilize our every moment to hear and to chant and to serve. This is the rule of the yatra to Dham. This is not necessarily a rule that we enforce, but it is a rule that we must discipline ourselves with by our free will. Every moment of life is precious. This human life is very rare, every moment is so precious. And the rarest of all things is the association of the Lord's devotees. Caitanya Mahaprabhu taught through Rupa Goswami, five very important principles, most important to make spiritual progress.They are – To associate with devotees, chant the holy names, to hear Srimad Bhagvatam, worship the deities and be in the holy dham. All of these 5 is really all we have. There is nothing else to do. We hear hari katha, we chant the holy names, and to perform such activities in the holy dham, even that is increased many folds here. We have such a rare opportunity to make such spiritual progress in short time while residing in dham.
