How wonderful it would be if all the friends could arrange to spend at least a few days in one of these summer schools and take an active part in their development. These centers could attract many souls if properly arranged and made interesting; those non-Bahá'ís who visit them will then have some time to get into the spirit of the place and make a study of the Cause... We constantly receive letters from people who become Bahá'ís by visiting one of these centers and obtaining the Message there. (From a letter written on behalf of Shoghi Effendi to an individual believer, received about 1 May 1932, quoted in ‘Bahá'í News’ 67, October 1932; The Compilation of Compilations, vol. I, Centers of Baha’i Learning)
