The psychic life must use more muscles, but the purpose behind their use should not primarily be utilitarian, as in some forms of modern education called technical. The true aim is that man may develop the co-ordination of movements needed for enriching the practical side of his psychic life. Otherwise the brain must develop a set of movements aside from the central psychic direction, and that brings revolution and disaster in the world. Work may not come first in the art of life, but self-perfection, self-realisation through work. In reality, this self-realisation achieved by movement must of necessity expand, and there are no limits to its expansion.”
