From The Kitáb-i-Íqán, The Book of Certitude By Bahá’u’lláh.
— This is the Day in which the testimony of the Lord hath been fulfilled, the Day in which the Word of God hath been made manifest, and His evidence firmly established. His voice is calling you unto that which shall profit you, and enjoineth you to observe that which shall draw you nigh unto God, the Lord of Revelation.

IN THE NAME OF OUR LORD, THE EXALTED, THE MOST HIGH.
— No man shall attain the shores of the ocean of true understanding except he be detached from all that is in heaven and on earth. Sanctify your souls, O ye peoples of the world, that haply ye may attain that station which God hath destined for you and enter thus the tabernacle which, according to the dispensations of Providence, hath been raised in the firmament of the Bayán.
The essence of these words is this: they that tread the path of faith, they that thirst for the wine of certitude, must cleanse themselves of all that is earthly—their ears from idle talk, their minds from vain imaginings, their hearts from worldly affections, their eyes from that which perisheth. They should put their trust in God, and, holding fast unto Him, follow in His way. Then will they be made worthy of the effulgent glories of the sun of divine knowledge and understanding, and become the recipients of a grace that is infinite and unseen, inasmuch as man can never hope to attain unto the knowledge of the All-Glorious, can never quaff from the stream of divine knowledge and wisdom, can never enter the abode of immortality, nor partake of the cup of divine nearness and favor, unless and until he ceases to regard the words and deeds of mortal men as a standard for the true understanding and recognition of God and His Prophets.
Consider the past. How many, both high and low, have, at all times, yearningly awaited the advent of the Manifestations of God in the sanctified persons of His chosen Ones. How often have they expected His coming, how frequently have they prayed that the breeze of divine mercy might blow, and the promised Beauty step forth from behind the veil of concealment, and be made manifest to all the world. And whensoever the portals of grace did open, and the clouds of divine bounty did rain upon mankind, and the light of the Unseen did shine above the horizon of celestial might, they all denied Him, and turned away from His face—the face of God Himself. Refer ye, to verify this truth, to that which hath been recorded in every sacred Book.
Ponder for a moment, and reflect upon that which hath been the cause of such denial on the part of those who have searched with such earnestness and longing. Their attack hath been more fierce than tongue or pen can describe. Not one single Manifestation of Holiness hath appeared but He was afflicted by the denials, the repudiation, and the vehement opposition of the people around Him. Thus it hath been revealed: “O the misery of men! No Messenger cometh unto them but they laugh Him to scorn.”1 Again He saith: “Each nation hath plotted darkly against their Messenger to lay violent hold on Him, and disputed with vain words to invalidate the truth.”2

Part One, pages 1 - 5
— Verily He Who is the Daystar of Truth and Revealer of the Supreme Being holdeth, for all time, undisputed sovereignty over all that is in heaven and on earth, though no man be found on earth to obey Him. He verily is independent of all earthly dominion, though He be utterly destitute. Thus We reveal unto thee the mysteries of the Cause of God, and bestow upon thee the gems of divine wisdom, that haply thou mayest soar on the wings of renunciation to those heights that are veiled from the eyes of men.
