5.17.11

_*
tatrāpi bhāratam eva varṣaṃ karma-kṣetram anyāny aṣṭa varṣāṇi svargiṇāṃ puṇya-śeṣopabhoga-sthānāni bhaumāni svarga-padāni vyapadiśanti //

11. Of all this terrestrial extent, this continent of Bharata alone, is *Karma kshetra*, (that is, the land where man's actions become the means of his future attainment), the remaining eight continents are only places of enjoyment for those that return from Swarga with some portion of their merit unexhausted and these are called "celestial spots" on earth.
