1912 - Abdul-Baha in America
30 May 1912 Talk at Theosophical Lodge Broadway and Seventy-ninth Street, New York
During this time the Master occupied Himself by writing Tablets in response to questions from both the Eastern and the Western friends. Today He gave an account of the lives of Varqá and Rúhu'lláh. He showed His great kindness to the sons of this martyr in the path of God, Mírzá Azíz'u'lláh Khán and Mírzá Valíyu'lláh Khán. The Master then told the friends about some of the precepts of the Cause. During these discourses, He said often:
I am the interpreter of the Writings of the Blessed Beauty, as explicitly designated by the Supreme Pen. All must obey. All matters pertaining to the Faith must be referred to the authorized interpreter. In the future all must turn to the divine House of Justice. (Mahmud's Diary)
1956 - Never must they let a day pass without teaching some soul,
". . . Never must they let a day pass without teaching some soul, trusting to Bahá'u'lláh that the seed will grow. The friends should seek pure souls, gain their confidence, and then teach that person carefully until he becomes a Bahá'í, and then nurture him until he becomes a firm and active supporter of the Faith.
. . Everyone must remember that it is the 'Holy Spirit that quickens' and therefore the teacher must become like a reed through with the Holy Spirit may reach the seeking soul.
