The example set by Maharaja Priyavrata in marking off different states is still followed. As indicated here, different classes of men are destined to live in different areas, and therefore the boundaries of various tracts of land, which are described here as islands, should be defined by different rivers, forests and hills. This is also mentioned in relation to Maharaja Prthu, who was born from the dead body of his father by the manipulation of great sages. Maharaja Prthus father was very sinful, and therefore a black man called Nisada was first born from his dead body. The Naisada race was given a place in the forest because by nature they are thieves and rogues. As animals are given places in various forests and hills, men who are like animals are also destined to live there. One cannot be promoted to civilized life unless one comes to Krsna consciousness, for by nature one is destined to live in a particular situation according to ones karma and association with the modes of nature. If men want to live in harmony and peace, they must take to Krsna consciousness, for they cannot achieve the highest standard while absorbed in the bodily concept of life. Maharaja Priyavrata divided the surface of the globe into different islands so that each class of men would live peacefully and not clash with the others. The modern idea of nationhood has gradually developed from the divisions made by Maharaja Priyavrata.
