Thus the seven dvîpas are surrounded by the seven oceans. The dimensions of a dvîpa tally with the dimensions of the sea preceding it (*i.e.*, surrounded by it). Both the dvîpas and the oceans have thus gradually grown in magnitude, a vast store of waters being called the ocean.—27-28. The root ‘Riṣi’ means to wander about in happiness; hence in these Varṣas all the four classes of people live happily.—29.
