With regard to the question that you had asked, Shoghi Effendi feels that as he has formerly said in Bahá'í meetings it is quite proper for some of the friends to deliver talks, but their speeches must have a direct bearing on the teachings of Bahá'u'lláh and our dear Master. It is not absolutely necessary that in all the meetings only the writings and utterances of Bahá'u'lláh and the Master should be read, but when lectures and talks are given they must bear either directly or indirectly on the Cause.
