The Guardian cherishes the hope that at the termination of your school this summer every one of the attendants will have derived such mental and spiritual benefits, and acquired such a fresh enthusiasm to serve as will enable him, upon his return to his local community, to labour with a determination and vigour that will excite the envy and admiration of his fellow-believers, and stimulate them to greater heights of consecration to the service of our beloved Cause. 
(From a letter dated 15 August 1938 written on behalf of Shoghi Effendi to the Central States Summer School; The Compilation of Compilations, vol. I, Centers of Baha’i Learning)
