The number 8 is generally considered to be an auspicious number by numerologists. The square of any odd number, less one, is always a multiple of 8 (for example, 9 - 1 = 8, 25 - 1 = 8 ´ 3, 49 - 1 = 8 ´ 6), a fact that can be proved mathematically.
In Babylonian myth there were seven spheres plus an eighth realm, the fixed stars, where the gods lived. As a result, 8 is often associated with paradise. Muslims believe that there are seven hells but eight paradises, signifying God's mercy. In Buddhism 8 is a lucky number, possibly because of the eight petals of the lotus, a plant associated with luck in India and a favourite Buddhist symbol.
