Vāyu said:: The Earth, the firmament, the heaven and what is remembered as Makar—these four Sthānas are remembered as Āvarṇakas (? Āvaraṇakas: ‘Sheaths of the worlds’). It is said that they are teeming with excellent abodes and some are without them. Those that arc Naimittikas (evolved by a cause), remain steady till Ābhūtasamplava (annihilation by merging into the Bhūtas i.e. Elements).
