Significance of Number 108:
Nine Planets:The 9 planets traveling through the 12 signs constitutes the whole of existence. 9 x 12 = 108
The 27 nakshatras or lunar constellations spread over the 4 elements – fire, earth, air, water or the 4 directions – north, south, east, and west. This also constitutes the whole of existence. 27 x 4 = 108
Consider the powers of 1, 2, and 3 in math: 1 to 1st power = 1; 2 to 2nd power = 4 (2×2); 3 to 3rd power = 27 (3x3x3). 1x4x27 = 108.
Astrology: There are 12 rasi (sun signs) of 30 degrees each in the zodiac. These rasi are connected to the Adityas (12 Sun gods) and the rasi are said to give the results of the Sun. The Sun is karaka (significant) for the 1st and the houses 9th houses. When you take each rasi and divide it into nine amsas (divisions) it creates the Navamsa (9th divisional chart). 30 degrees divided by nine gives 9 signs of 3 degrees and 20 minutes each. With each of the 12 signs containing 9 amsas there is 108 amsas. This Navamsa shows the inherent qualities of the soul, a native’s dharma (purpose), bhagya (luck), and one’s spouse. The Navamsa is the 108 sign chart held in high esteem in Vedic astrology and a Vedic astrologer doesn’t read a birth chart without the navamsa sitting next to it.
