The process of normalisation is a natural journey.

After a period of intense concentration and working with materials that fully engage their interest children appear to be refreshed and contented.

Her observation, especially on the spiritual dimension of normalized children, is supported by other philosophers and educators such as Pestalozzi (1746-1827), his student Froebel (1782-1852), and later Rudolph Steiner (1861-1925), all of who had similar revolutionary views on modern education. They were pioneers in the holistic education movement believing that education should contribute to the spiritual development of children. Like Montessori, they viewed the young child as more than just a growing body and mind. They saw a spiritual dimension to human development as well.
Pestalozzi’s motto was "Learning by head, hand and heart". His philosophy of education was based on a four-sphere concept of life and the premise that human
