Conventional theories presume the lands where Angkor stands were chosen as a settlement site because of their strategic military position and agricultural potential. Alternative scholars, however, believe the geographical location of the Angkor complex and the arrangement of its temples was based on a planet-spanning sacred geography from archaic times. Using computer simulations, it has been shown that the ground plan of the Angkor complex – the terrestrial placement of its principal temples – mirrors the stars in the constellation of Draco at the time of spring equinox in 10,500 BC. While the date of this astronomical alignment is far earlier than any known construction at Angkor, it appears that its purpose was to architecturally mirror the heavens in order to assist in the harmonization of the earth and the stars. Both the layout of the Angkor temples and the iconographic nature of much its sculpture, particularly the asuras (‘demons’) and devas (‘deities’) are also intended to indicate the celestial phenomenon of the precession of the equinoxes and the slow transition from one astrological age to another.
Angkor Wat, built during the early years of the 12th century by Suryavaram II, honors the Hindu god Vishnu and is a symbolic representation of Hindu cosmology. Consisting of an enormous temple symbolizing the mythic Mt. Meru, its five inter-nested rectangular walls and moats represent chains of mountains and the cosmic ocean. The short dimensions of the vast compound are precisely aligned along a north-south axis, while the east-west axis has been deliberately diverted 0.75 degrees south of east and north of west, seemingly in order to give observers a three day anticipation of the spring equinox.
Orthodox archaeologists sometimes interpret the temples of the Angkor complex as tombs of megalomaniacal kings yet in reality those kings designed and constructed the temples as a form of service to both god and their own subjects. The temples were places not for the worship of the kings but rather for the worship of god. Precisely aligned with the stars, constructed as vast three dimensional yantras and adorned with stunningly beautiful religious art, the Angkor temples were instruments for assisting humans in their realization of the divine.
Jayavaram VII, spoke of his intentions in erecting temples as being:
“full of deep sympathy for the good of the world, so as to bestow on men the ambrosia of remedies to win them immortality….By virtue of these good works would that I might rescue all those who are struggling in the ocean of existence.”Source : SacredSites.com
