The third Tajallí is concerning arts, crafts and sciences. Knowledge is as wings to man’s life, and a ladder for his ascent. Its acquisition is incumbent upon everyone. The knowledge of such sciences, however, should be acquired as can profit the peoples of the earth, and not those which begin with words and end with words. Great indeed is the claim of scientists and craftsmen on the peoples of the world. Unto this beareth witness the Mother Book on the day of His return. Happy are those possessed of a hearing ear. In truth, knowledge is a veritable treasure for man, and a source of glory, of bounty, of joy, of exaltation, of cheer and gladness unto him. Thus hath the Tongue of Grandeur spoken in this Most Great Prison. The fourth Tajallí is concerning Divinity, Godhead and the like. Were a man of insight to direct his gaze towards the blessed, the manifest Lote-Tree and its fruits, he would be so enriched thereby as to be independent of aught else and to acknowledge his belief in that which the Speaker on Sinai hath uttered from the throne of Revelation. O ‘Alí-Akbar! Acquaint the people with the holy verses of thy Lord and make known unto them His straight Path, His mighty Announcement. Say: O people, if ye judge fairly and equitably, ye will testify to the truth of whatsoever hath streamed forth from the Most Exalted Pen. If ye be of the people of the Bayán, the Persian Bayán will guide you aright and will prove a sufficient testimony unto you; and if ye be of the people of the Qur’án, ponder ye upon the Revelation on Sinai and the Voice from the Bush which came unto the Son of ‘Imrán [Moses]. Gracious God! It was intended that at the time of the manifestation of the One true God the faculty of recognizing Him would have been developed and matured and would have reached its culmination. However, it is now clearly demonstrated that in the disbelievers this faculty hath remained undeveloped and hath, indeed, degenerated. O ‘Alí! That which they accepted from the Bush they now refuse to accept from Him Who is the Tree of the world of existence. Say, O people of the Bayán, speak not according to the dictates of passion and selfish desire. Most of the peoples of the earth attest the truth of the blessed Word which hath come forth from the Bush.
