*Trivia: "[....] It is well known that the Egyptians had a system of astronomical calculations some 50,000 years before Alexander the Great, which set off dates, months and years by mathematical numbers. This was the duo-decimal system, or method of reckoning by 12 in common use. It is by the use of this system in the construction of the pyramids, that the origin of the English foot of 12 inches has been traced. Among the early races the decimal system or reckoning by 10, was esoteric and known only to the higher initiates. [NP] Much of the system which was in early use during these times was due to the efforts of Gopal Das who was the living ECK Master during these times. He introduced a simple system which was considered the duo-decimal system which is the reckoning by 12 in common use. The priestcraft tried to withold it from the public, but he was able to give out enough information especially among the ECK disciples of his times, and gradually in the centuries that followed it became better known and eventually found favor in public education. [NP] Naturally in the early days of man the decimal system was held sacred because the esoteric leaders thought it was received from the higher powers. [NP] We know the decimal system was used by mankind of the earliest archaic ages, since the whole astronomical and geometrical portion of the secret sacerdotal language was built upon the number 10, or the combination of the male and female principles. The 10, being the sacred number of the universe, was secret and esoteric, both as regards the unit and cipher, or zero, the circle. [....]"
