The womb of a mother is a wonderful factory. The wonderful aspect of the human produce is that it conforms to a ‘fixed proportion’. There is a constant balance between ‘demand and supply’. For instance, this wonderful plant which has been working for thousands of years, produces men as well as women, but a constant proportion is maintained between these two sexes. It never happens that this plant produces males only or females only. An event like war sometimes temporarily disturbs this proportion. But it has been observed, strangely enough, that after a certain period this original proportion is soon restored. The same is true of the balance of talent in the men and women coming out of this plant. Research has shown that those being born are not of a uniform capacity. There is a great diversity in their talents. This diversity is of importance in civilization, because persons of diverse capacities are required to manage the affairs of a civilization. The plant of mothers is quietly and successfully producing persons with different talents, as if it were receiving ‘orders’ from outside which led to how the persons in the womb were constituted. If there had not been this diversity in the production of human beings, the whole system of civilization would have descended into chaos and all development would have ceased. The existence of this planning in the working of the mother’s womb clearly shows that there is a Planner behind it. Without conscious planning, a system marked by such regularity could never exist. This also proves that the Creator and Lord of this world is a Being Who is aware not only of whatever is plain for everyone to see, but also of what is unseen and hidden. Whatever happens in a woman’s womb is apparently a secret matter. But the above-mentioned details show that God is completely aware of it. Then this Being Who is aware of the open and hidden aspects of everything is bound to know the hidden, and open aspects pertaining to human beings. Belief in angels is also proved by this, because it is an extension of the present system of keeping ‘watch’.
