The teacher whose physical powers are already enfeebled by disease or overwork should pay especial attention to the laws of health. He should take time for recreation. When a teacher sees that his health is not sufficient to stand the pressure of heavy study, he should heed the admonition of nature and lighten the load. He should not take upon himself responsibilities outside of his schoolwork which will so tax him physically and mentally that his nervous system will be unbalanced, for by this course he will be unfitted to deal with minds and cannot do justice either to himself or to his students. {CT 300.3}

Den lærer hvis fysiske kræfter allerede er svækket af sygdom eller overarbejdet bør være særlig opmærksom på sundhedslovene. Han bør tage sig tid til rekreation. Når en lærer ser at hans sundhed ikke er nok til at modstå presset af hårde studier, bør han give agt på naturens formaning og lette lasten. Han bør ikke påtage sig ansvar uden for (301) sit skolearbejde, som vil belaste ham fysisk og mentalt, så hans nervesystem vil komme ud af balance, for derved vil han ikke være rustet til at have med menneskesind at gøre og kan ikke handle ret, hverken mod sig selv eller mod sine studerende.
