Growth and psychic development are therefore guided by: the absorbent mind, the nebulae and the sensitive periods, with their respective mechanisms. It is these that are hereditary and characteristic of the human species. But the promise they hold can only be fulfilled through the experience of free activity conducted in the environment.

The development of the mind comes through movement

Independence is not a static condition; it is a continuous conquest, and in order to reach not only freedom, but also strength, and the perfecting on one's powers, it is necessary to follow this path of unremitting toil.

The essence of independence is to be able to do something for one’s self. Adults work to finish a task, but the child works in order to grow, and is working to create the adult, the person that is to be. Such experience is not just play... it is work he must do in order to grow up.

The child's conquest of independence begins with his first introduction to life. While he is developing, he perfects himself and overcomes every obstacle that he finds in his path. A vital force is active within him, and this guides his efforts towards their goal. It is a force called the 'horme', by Sir Percy Nunn.

The first essential for the child’s development is concentration. The child who concentrates is immensely happy.

The child has other powers than ours, and the creation he achieves is no small one; it is everything.
