First, know that above and beyond our familiar earth are the realms called Bhūrloka, Bhuvarloka, Svarloka, and likewise Maharloka. These are the worlds, each one extending further than the last, marking the boundaries of creation itself. This, indeed, is the true extent of the universe, and the furthest reach of the worlds. From the very beginning of the bright fortnight, the universe takes the form of a vast cosmic egg. Whether one looks across, above, or below, this cosmic egg is fashioned from the imperishable essence of the ultimate cause. Each world supports the next, with each successive realm exceeding the previous by tenfold, creating a wondrous, layered structure. Surrounding this cosmic egg on all sides is a dense, encircling ocean. Beyond this ocean, its sphere extends outward in every direction, both across and above. Encasing all is the region of fire, perfectly round and glowing, like a massive shell of iron. This fiery region steadfastly supports the layers of dense wind and space, holding them in place. Yet, even this great structure is itself upheld by something vaster still—the infinite and unmanifest. This great principle is infinite, self-existent, without beginning or end. Its boundaries are separated by thousands of yojanas, stretching beyond all measure. Not even the gods can fully know it, for it is beyond all dealings and comprehension. This, then, is the supreme abode, the boundary of the infinite God. These boundaries, established for the great Lord of gods, are known as the worlds of the universe, without any doubt. Within them are seven distinct layers, O twice-born, as well as the abodes of Brahma. Thus is measured the entire universe—this is the ocean of transmigration, the endless cycle of birth and rebirth. Marvel at this wondrous nature of the universe, for it is none other than the very nature of Brahman itself. Even the most blessed and perfected beings cannot perceive it through the senses. O best of the twice-born, this is the mental body of the infinite one, spoken of everywhere in the sacred teachings. He who is called Padmanabha is described in this way, in his entirety. On earth, in the netherworld, in the sky, in the wind, and in fire, and even in darkness—he alone is the great radiant one to be known. In all worlds, the mighty Lord of worlds is worshipped in many forms. All these layers and worlds are bound together by the relation of support and supported, yet all modifications belong to the one who is unchanging. They interpenetrate each other, each being superior in various ways. In the beginning, all was undifferentiated; only later did distinctions arise as diversity unfolded from unity. Through the accumulation of qualities, separation became clear and distinct. Beyond the elements, and even further, there is an illumination that is known as earth. Just as smaller vessels are contained within a larger one, so too are the divisions of illumination within space considered to be contained within greater divisions. As long as these elements exist, their origin is spoken of; but when the elements are withdrawn, all effects cease to be produced. These divisions, beginning with the great principle, are of the nature of causes, and they are fundamentally one. O twice-born, the regions of the seven continents and oceans exist as they truly are, but all these transformations pertain only to a part of the universal form of the chief principle. Thus, seven groups of such beings are established together in this grand design. Let this much be heard, then, about the wondrous arrangement of the earthly realm.
