Srila Prabhupada's hut in Mayapur
"In the spiritual sky all the planets dominated by the Narayana feature are eternal. The topmost planet in the spiritual sky is called Krsnaloka and is divided into three different portions: Gokula, Mathura and Dvaraka. In the Mathura portion, the form of Kesava is always situated. He is also represented on this earthly planet. In Mathura, India, the Keshava murti is worshiped, and similarly there is a Purusottama form in Jagannatha Puri in Orissa. In Anandaranya there is the form of Visnu, and in Mayapur, the birthplace of Lord Caitanya, there is the form of Hari. Many other forms are also situated in various places on the earth. Not only in this universe but in all other universes as well the forms of Krsna are distributed everywhere. It is indicated that this earth is divided into seven islands, which are the seven continents, and it is understood that on each and every island there are similar forms, but at the present moment these are only found in India."
