At exactly the same moment in human evolutionary history—1910 to 1920—three men who were primarily spiritual teachers each independently articulated an integral model of human development from birth to age 21. These three men were Rudolf Steiner, Aurobindo Ghose, and Inayat Khan, and their common visionof human development included the physical and the intellectual, the emotional and the spiritual, and the complex and intimate relationships among these four aspects of each human being. These three men also used the term unfoldmentrather than developmentto indicate that the growth of the child was not only a progression of increasing complexity but also an ongoing, outer expression of inner potentials.      

Each of them also taught explicitly about the manifestation of evolution on this planet. Theircommon visiontells us how we can raise and educate our children so that they can embody their potential—so they can access post-modern consciousness in their teens and integral consciousness in their early twenties—and so we can evolve as a species through and beyond the dangers of our current global challenges.
