"Unlock, then, to their hearts, O my God, the portals of Thy knowledge ..."

"Praise be unto Thee, O my God! Thou art He Who by a word of His mouth hath revolutionized the entire creation, and by a stroke of His pen hath divided Thy servants one from another. I bear witness, O my God, that through a word spoken by Thee in this Revelation all created things were made to expire, and through yet another word all such as Thou didst wish were, by Thy grace and bounty, endued with new life. ...

Unlock, then, to their hearts, O my God, the portals of Thy knowledge, that they may recognize Thee as One Who is far above the reach and ken of the understanding of Thy creatures, and immeasurably exalted above the strivings of Thy people to hint at Thy nature, and may not follow every clamorous impostor that presumeth to speak in Thy name. Enable them, moreover, O my Lord, to cleave so tenaciously to Thy Cause that they may remain unmoved by the perplexing suggestions of them who, prompted by their desires, utter what hath been forbidden unto them in Thy Tablets and Thy Scriptures."

"The Prophets and Messengers of God have been sent down for the sole purpose of guiding mankind to the straight Path of Truth."

"The Prophets and Messengers of God have been sent down for the sole purpose of guiding mankind to the straight Path of Truth. The purpose underlying their revelation hath been to educate all men, that they may, at the hour of death, ascend, in the utmost purity and sanctity and with absolute detachment, to the throne of the Most High…."

"Special regard must be paid to agriculture."

... "Fifth:  Special regard must be paid to agriculture. Although it hath been mentioned in the fifth place, unquestionably it precedeth the others. Agriculture is highly developed in foreign lands, however in Persia it hath so far been grievously neglected. It is hoped that His Majesty the Sháh—may God assist him by His grace—will turn his attention to this vital and important matter."

"Know thou that whoso seeketh to scale the summits of the divine mysteries must needs strive to the utmost of his power and capacity for his Faith, that the pathway of guidance may be made clear unto him."

"O thou who art standing before My Throne and yet remain unaware thereof!  Know thou that whoso seeketh to scale the summits of the divine mysteries must needs strive to the utmost of his power and capacity for his Faith, that the pathway of guidance may be made clear unto him. And should he encounter One Who layeth claim to a Cause from God, and Who holdeth from His Lord a testimony beyond the power of men to produce, he must needs follow Him in all that He pleaseth to proclaim, command and ordain, even were He to decree the sea to be land, or to pronounce earth to be heaven, or that the former lieth above the latter or below it, or to ordain any change or transformation, for He, verily, is aware of the celestial mysteries, the unseen subtleties, and the ordinances of God."

"The source of all learning is the knowledge of God ..."

"The source of all learning is the knowledge of God, exalted be His Glory, and this cannot be attained save through the knowledge of His Divine Manifestation."

"As the body of man needeth a garment to clothe it, so the body of mankind must needs be adorned with the mantle of justice and wisdom."

"And now concerning thy question regarding the nature of religion. Know thou that they who are truly wise have likened the world unto the human temple. As the body of man needeth a garment to clothe it, so the body of mankind must needs be adorned with the mantle of justice and wisdom. Its robe is the Revelation vouchsafed unto it by God. Whenever this robe hath fulfilled its purpose, the Almighty will assuredly renew it. For every age requireth a fresh measure of the light of God. Every Divine Revelation hath been sent down in a manner that befitted the circumstances of the age in which it hath appeared."

"Behold, O concourse of the earth, the splendours of the End, revealed in the Manifestations of the Beginning!"

"O my beloved! Immeasurably exalted is the celestial Melody above the strivings of human ear to hear or mind to grasp its mystery! How can the helpless ant step into the court of the All-Glorious? And yet, feeble souls, through lack of understanding, reject these abstruse utterances, and question the truth of such traditions. Nay, none can comprehend them save those that are possessed of an understanding heart. Say, He is that End for Whom no end in all the universe can be imagined, and for Whom no beginning in the world of creation can be conceived. Behold, O concourse of the earth, the splendours of the End, revealed in the Manifestations of the Beginning!"
