Anything-Nothing

My 4-year-old daughter says "anything" for "nothing." Today I asked her, "What do you have in your hand?" Her reply, "Anything." Last week, when she and a friend were playing, I asked, "What are you doing?" Again, she said, "Anything."

Her word choice may simply be a 4-year-old's confusion, or a sign of language development that will soon mature and self-correct. However, each time I hear her, she cuts through my view that something "is" or "is not." It can't be both at the same time--you either have something in your hand or you do not. But for her, it could be "anything," which leaves open all possibilities, including "nothing."

...Form does not differ from emptiness, 
emptiness does not differ from form. 
Form itself is emptiness, emptiness itself form.
