The Kitáb-i-Aqdas - The Most Holy Book
Index term: Dust
k36.
Amongst the people is he who seateth himself amid the sandals by the door whilst coveting in his heart the seat of honour. Say: What manner of man art thou, O vain and heedless one, who wouldst appear as other than thou art? And among the people is he who layeth claim to inner knowledge, and still deeper knowledge concealed within this knowledge. Say: Thou speakest false! By God! What thou dost possess is naught but husks which We have left to thee as bones are left to dogs. By the righteousness of the one true God! Were anyone to wash the feet of all mankind, and were he to worship God in the forests, valleys, and mountains, upon high hills and lofty peaks, to leave no rock or tree, no clod of earth, but was a witness to his worship -- yet, should the fragrance of My good pleasure not be inhaled from him, his works would never be acceptable unto God. Thus hath it been decreed by Him Who is the Lord of all. How many a man hath secluded himself in the climes of India, denied himself the things that God hath decreed as lawful, imposed upon himself austerities and mortifications, and hath not been remembered by God, the Revealer of Verses. Make not your deeds as snares wherewith to entrap the object of your aspiration, and deprive not yourselves of this Ultimate Objective for which have ever yearned all such as have drawn nigh unto God. Say: The very life of all deeds is My good pleasure, and all things depend upon Mine acceptance. Read ye the Tablets that ye may know what hath been purposed in the Books of God, the All-Glorious, the Ever-Bounteous. He who attaineth to My love hath title to a throne of gold, to sit thereon in honour over all the world; he who is deprived thereof, though he sit upon the dust, that dust would seek refuge with God, the Lord of all Religions.
k76.
God hath enjoined upon you to observe the utmost cleanliness, to the extent of washing what is soiled with dust, let alone with hardened dirt and similar defilement. Fear Him, and be of those who are pure. Should the garb of anyone be visibly sullied, his prayers shall not ascend to God, and the celestial Concourse will turn away from him. Make use of rose-water, and of pure perfume; this, indeed, is that which God hath loved from the beginning that hath no beginning, in order that there may be diffused from you what your Lord, the Incomparable, the All-Wise, desireth.
k148.
Ye have been forbidden in the Book of God to engage in contention and conflict, to strike another, or to commit similar acts whereby hearts and souls may be saddened. A fine of nineteen mithqáls of gold had formerly been prescribed by Him Who is the Lord of all mankind for anyone who was the cause of sadness to another; in this Dispensation, however, He hath absolved you thereof and exhorteth you to show forth righteousness and piety. Such is the commandment which He hath enjoined upon you in this resplendent Tablet. Wish not for others what ye wish not for yourselves; fear God, and be not of the prideful. Ye are all created out of water, and unto dust shall ye return. Reflect upon the end that awaiteth you, and walk not in the ways of the oppressor. Give ear unto the verses of God which He Who is the sacred Lote-Tree reciteth unto you. They are assuredly the infallible balance, established by God, the Lord of this world and the next. Through them the soul of man is caused to wing its flight towards the Dayspring of Revelation, and the heart of every true believer is suffused with light. Such are the laws which God hath enjoined upon you, such His commandments prescribed unto you in His Holy Tablet; obey them with joy and gladness, for this is best for you, did ye but know.
k150.
Teach your children the verses revealed from the heaven of majesty and power, so that, in most melodious tones, they may recite the Tablets of the All-Merciful in the alcoves within the Mashriqu'l-Adhkárs. Whoever hath been transported by the rapture born of adoration for My Name, the Most Compassionate, will recite the verses of God in such wise as to captivate the hearts of those yet wrapped in slumber. Well is it with him who hath quaffed the Mystic Wine of everlasting life from the utterance of his merciful Lord in My Name -- a Name through which every lofty and majestic mountain hath been reduced to dust.

and when the Sun of Truth and Utterance shall set, turn your faces towards the Spot that We have ordained for you
Bahá’u’lláh ordains His resting-place as the Qiblih after His passing. The Most Holy Tomb is at Bahjí­, 'Akká. ‘Abdu’l-Bahá describes that Spot as the “luminous Shrine”, “the place around which circumambulate the Concourse on High”.
In a letter written on his behalf, Shoghi Effendi uses the analogy of the plant turning in the direction of the sun to explain the spiritual significance of turning towards the Qiblih:

. . . just as the plant stretches out to the sunlight -- from which it receives life and growth -- so we turn our hearts to the Manifestation of God, Bahá’u’lláh, when we pray; . . . we turn our faces . . . to where His dust lies on this earth as a symbol of the inner act.
