When and why was the difference of sex produced in manifestation? One cannot say that the soul of woman or the soul of man was made first, as the soul is neither male nor female. When the soul reaches the point where the distinction of sex arises, it is first male; then if it wishes to become finer, it becomes female. We can see in the kernel of the almond and of other nuts, that where there are two kernels in one shell the female form has been formed from the male.
