"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!"

-Bahá'u'lláh, The Kitáb-i-Íqán,p. 168

" ... accept from Thy servants what they are capable of showing forth in Thy path."

..."I bear witness that the highest thoughts of all such as adore Thy unity, and the profoundest contemplations of all them that have recognized Thee, are but the product of what hath been generated through the movement of the Pen of Thy behest, and hath been begotten by Thy will. I swear by Thy glory, O Thou Who art the Beloved of my soul and the Fountain of my life! I am persuaded of my powerlessness to describe and extol Thee in a manner that becometh the greatness of Thy glory and the excellence of Thy majesty. Aware as I am of this, I beseech Thee, by Thy mercy that hath surpassed all created things, and Thy grace that hath embraced the entire creation, to
accept from Thy servants what they are capable of showing forth in Thy path. Aid them, then, by Thy strengthening grace, to exalt Thy word and to blazon Thy praise." ...
