In order for men and women to have well-balanced minds, all the powers of the being should be called into use and developed. There are in this world many who are one-sided because only one set of faculties has been cultivated, while others are dwarfed from inaction. The education of many youth is a failure. They overstudy, while they neglect that which pertains to the practical life. That the balance of the mind may be maintained, a judicious system of physical work should be combined with mental work that there may be a harmonious development of all the powers. {CT 295.3}

For at mænd og kvinder kan få et velafbalanceret sind, må alle kræfter bruges og udvikles. I denne verden er der mange som er ensidige, kun fordi en slags evner bliver opdyrket, medens andre gøres små af inaktivitet. Mange unges uddannelse er en fiasko. De studerer for meget, medens de forsømmer det der angår det praktiske liv. (296) Om sindets balance bliver fastholdt, bør et sundt fysisk arbejde kombineres med mentalt arbejde, så de kan få en harmonisk udvikling af alle kræfter.
