Shoghi Effendi sincerely hopes that through the activities of you and the other teachers now in Europe the Cause will make a great move and many centres will be established in Central Europe. It is very important to have regular study classes to follow public lectures, so that those who become interested may not go astray. Mrs. [Louise] Gregory can be of great service along this line of grounding the few who are deeply attracted, in the teachings of the Cause. (From a letter dated 24 May 1932 written on behalf of Shoghi Effendi to an individual believer; compilation ‘Eastern Europe and the Soviet Union,’ prepared by the Research Department of the Universal House of Justice)
