yāni kiṃpuruṣādīni varṣāṇy aṣṭau mahāmune
teṣāṃ svābhāvikī siddhiḥ sukhaprāyā hy ayatnataḥ //

The eight Varshas, or countries, Kimpurusha and the rest, are places of perfect enjoyment, where happiness is spontaneous and uninterrupted. In them there is no vicissitude, nor the dread of decrepitude or death: there is no distinction of virtue or vice, nor difference of degree as better or worse, nor any of the effects produced in this region by the revolutions of ages.
