Caption: A child completes mothers personality
The picture to me depicts the phenomenon of birth. We can clearly see the female figure depicting the mother. The mother is having a bleeding womb during the birth.
At the time of birth, a new individual is born(child) and along with it the new personality of mother is born too. The child is the sculpture of the new identity of mother. The child is shown to have a hammer in hand which shows that.
The child is being detached from the womb of the mother by a Doctor which is shown by a hand dragging the child.
As a new born child has its identity defined by the mother, she gives him the weapons to further develop her personality by doing deeds which will make her feel proud and add value to her personality too. As most of the deeds done by an individual directly or indirectly relates to the teachings of the mother.
