(chapter summary from God and Science by Richard L. Thompson)
The Srimad-Bhagavatam describes the Bhu-mandala, the Universe. At first glance these descriptions are inconsistent and constantly contract one another. However, when viewed with the correct understanding, it all makes sense.
Bhu-mandala simultaneously describes four things:
- a topographical map of south-central Asia
- a polar-projection map of the Earth
- a map of the solar system
- a map of the celestial heavens of the demigods
Bhu-mandala can be seen as a topographical maps of south-central Asia. The various peaks of the Himalayan mountains are accurately depicted on the North/top of the map.
The Bhagavatam certainly doesn't have the primitive idea that the Earth flat. There are plenty of indirect references to a globe-shaped Earth. Bhu-mandala, understood as a map of the Earth, is an astrological map. Lines on the map show the exact orbital paths of various stars and planets from the Earth's perspective.
Bhu-mandala can also be taken as a map of the solar system up to Saturn. The orbits of the planets in the solar system lie on a nearly flat plane, so the flatness of the map does not cause any trouble here. Furthermore, the distances given in the Bhagavatam closely match the recent astronomical measurements.
Finally, Bhu-mandala, viewed as a map of the paradisiacal lands of the demigods, explains the extremely large distances which are sometimes quoted in the text. For example: India is described to be 72,000 miles across (3 times the circumference of the Earth). This is no mistake, after all demigods like Lord Siva are said to be nearly the size of Europe.
The various maps are overlaid because they are interconnected. Mystic yogis could use the various points of interconnection as "short-cuts" through space in order to very quickly transport themselves between Earth, the celestial realms and other planets.
