I read one book (MAN IS THE EXTENSION OF WOMAN) Here is one equation But look at the man. He is something more. He is X and Y. That means, he is essentially an ‘X ’plus something extra. What do I mean by that! Man is already a woman that is ‘X’, plus something extra. Does that mean first step towards manhood is womanhood? Now let’s talk in mathematical language. Here is the equation, Man = 22 autosomes + X + Y Woman= 22 autosomes + X + X= 22 autsomes + X (by logic not by mathematics). . . Man= (22 autosomes + X) + Y= Woman + Y (by mathematics, simply) So man is everything that woman is, plus something extra. Now the extra thing is not qualitatively different, but quantitatively. Hence Y here must be somewhat like X + 1, X+2 or X+ 3 or something like that. It would be ultimately proven that woman can potentially grow into man. Similarly man can reduce to woman, if he loses some part of ‘Y’. What does it suggest?
