360º x 30º = 10,800

360º x 30º = 10,800 Thus the 360º x 30º = 10,800. Zero {0} is considered ‘Purna’ or complete. So we take out the last zeros and are left with 108. The idea of our total universe is represented by this number of 108. Offering 108, devotees believe that they are showing ultimate or complete respect to the Supreme.
