Tahirih was transformed by Baha’u’llah ...

Qurratu'l-‘Ayn was a Persian woman without fame and importance -unknown, like all other Persian women. When she saw Baha'u'llah, she changed completely, visibly, and looked within another world. The reins of volition were taken out of her hands by heavenly attraction. She was so overcome that physical susceptibilities ceased. Her husband, her sons and her family arose in the greatest hostility against Baha'u'llah. She became so attracted to the divine threshold that she forsook everything and went forth to the plain of Badasht, no fear in her heart, dauntless, intrepid, openly proclaiming the message of light which had come to her. The Persian government stood against her. They made every effort to quiet her, they imprisoned her in the governor's house, but she continued to speak. Then she was taken and killed. To her very last breath she spoke with fervid eloquence and so became famous for her complete attraction in the path of God. If she had not seen Baha'u'llah, no such effect would have been produced. She had read and heard the teachings of scriptures all her life, but the action and enkindlement were missing. (‘Abdu’l-Baha, ‘Promulgation of Universal Peace’, Page 251)
