“Yá Bahá'u'l-Abhá – This is an invocation. It means "O Glory of the All-Glorious." In this connection we recall the soul stirring message of the Guardian in 1953 to the Intercontinental Conferences where he refers to "Yá Bahá'u'l-Abhá" and "Yá `Aliyyu'l-'Ala" as the "battle cry" of the pioneers and teachers in the many fields of this world-embracing spiritual Crusade. The first, as already stated, means "O Glory of the All-Glorious", while the second means "O Exalted of the Most Exalted One." - Abu'l-Qasim Faizi
