In these addresses also we find vivid and inspiring pictures of the latent possibilities of the human soul and the new civilization which shall arise from the influence of the Holy Spirit. The adaptability of ‘Abdu’l-Bahá to the particular audience or individual inquirer produced a true unity between groups and interests never reconciled before. No such source of education in the whole meaning of the word exists in the modern world outside the writings of ‘Abdu’l-Bahá. In these writings the ideals of Christian, Jew and other religionists, of philosopher and scientist, of economist and reformer are abundantly realized.

At the time of the passing of ‘Abdu’l-Bahá, The Bahá’ís existed in many countries of the East and West. To these He left explicit instructions explaining and applying the teachings of Bahá’u’lláh, concerning the method of unifying the believers and administering the work of the Cause. He appointed in His Will and Testament His eldest grandson, Shoghi Effendi, as first Guardian of the Cause, and left directions for the election of an International Council (Baytu’l-‘Ahd’l, ·i. e., House of Justice) based on the universal suffrage of the believers, which should in conjunction with him guide the development of the Movement and co-ordinate the activities of its followers in accordance with the principles laid down by Bahá’u’lláh.
