As an illustration, I sometimes use the fingers and the palm of the hand. Each finger represents a religion. The baby finger is Buddhism, the next is Hinduism, the middle one is Islam, the forefinger is Judaism, and the thumb is Christianity. Buddhism is miles from Christianity. And they are all divided separately, but as you go deep into any religion, you converge on the center, and everything springs from that center and converges at that center, which is how we are today.
