There is still a third, even less well known, capacity that we learn on our own through what we bear within us through successive incarnations. I am referring here to our ability to live within the world of thoughts and ideas, the world of thought itself. Our brain is formed and worked on because it is the tool of thinking. At the beginning of life, the brain is still malleable because we must shape it ourselves to make it an instrument for the thinking appropriate to our essential being. The brain at birth is the result of the work of forces inherited from our parents, grandparents, and so on. It is in our thinking that we bring to expression what we are as individuals in conformity with our former earthly lives. Therefore, after birth, when we have become physically independent of our parents and ancestors, we must transform the brain we have inherited.
