Mr. Taherzadeh speaks in English adding his own Persian translation between comments. 

Among Baha’u’llah’s children Abdu’l-Baha and Bahiyyih Khanum became great spiritual giants. He gives examples of how an insignificant person becomes a spiritual giant when they are devoted to teaching the Faith. None of the other children of Baha’u’llah achieved such high spiritual stations. Mirza Muhammad Ali—one of Baha’u’llah’s children—was endowed with great capacity; but he didn’t became a spiritual giant; instead he became a despicable Covenant-Breaker.
