The other relations besides the odd and even in Numerology

 There are other relations besides the odd and even.  Each number can be viewed as the next logical development following the stage represented by the previous number. The independence of the 1, for instance, is followed by the cooperation with others of the 2; the constructive freedom of the 5 is followed by the balance and responsibility of the 6. From a different perspective, each number represents the opposite of the previous number: the limitation of the 4 is followed by the constructive freedom of the 5, the material satisfaction of the 8 is followed by the selflessness of the 9.
