Bahá’Ãyyih Khánum, known as the Greatest Holy Leaf, is a unique figure in the annals of the Bahá’à Faith. Her lifelong heroic services to Bahá’u’lláh’s Cause pinnacled after `Abdu’l-Bahá’s ascension. The vital role she played at that crucial juncture ensured the smooth running of the affairs of the worldwide Bahá’à community until Shoghi Effendi, the Guardian of the Cause of God, appointed by the Centre of Bahá’u’lláh’s Covenant arrived in Haifa a month after `Abdu’l-Bahá’s passing. She was the staunchest supporter and confidant of Shoghi Effendi, ever ready, despite advanced age, to accomplish the formidable tasks she was required to undertake. This webinar is about her services during the crucial first decade of the second Age of the Bahá’à Era.
