What for you want to go on world tour — people everywhere are doing the same thing, eating, sleeping, mating, and defending — each in some slightly different way, but same substance is there. There are the same streets, same people, same cars, same trees, etc. everywhere, somewhere a hill, somewhere sandy, somewhere some water — but what is the profit of seeing so much scenery? It is better if you want to travel, you can travel to preach and spread this Krishna Consciousness to the suffering humanity at large.
From Srila Prabhupada’s letter to: Kris — Los Angeles 13 November, 1968
