The soul of a child who has just incarnated is already in possession of all its faculties, but it is not yet able to manifest in all its power

"Contrary to appearances, the psychic development of a human being does not coincide with his physical growth. It is a mistake to believe that when a child comes to earth, his soul, his moral and intellectual faculties, follow the growth of his body, and that later on, as his body ages, weakens and loses its vitality, his soul does the same. No, the soul of a child who has just incarnated is already in possession of all its faculties, but it is not yet able to manifest in all its power. This is why the soul works on the child’s physical body while largely outside of it, until it can inhabit the body fully. In the process it encounters many difficulties, of course, but this is what it is trying to do throughout a person’s life. If, as the years go by, man seems to be blessed with new faculties and talents, even into old age, it is because the soul continues to take possession of his body and to express itself through it."
