Cleanliness and sanctity in all conditions are characteristics of pure beings and necessities of free souls. The first perfection consists in cleanliness and sanctity and in purity from every defect. When man in all conditions is pure and immaculate, he will become the center of the reflection of the manifest Light. In all his actions and conduct there must first be purity, then beauty and independence. The channel must be cleansed before it is filled with sweet water. The pure eye comprehendeth the sight and the meeting of God; the pure nostril inhaleth the perfumes of the rose-garden of bounty; the pure heart becometh the mirror of the beauty of truth. This is why, in the heavenly Books, the divine counsels and commands have been compared to water. So, in the Qur'án it is said, "and we have caused a pure water to descend from heaven;" and in the Gospel, "Except a man hath received the baptism of water and of the spirit, he cannot enter into the Kingdom of God." Then it is evident that the divine teachings are the heavenly grace and the showers of the mercy of God, which purify the hearts of men.
The meaning is, in all conditions, cleanliness and sanctity, purity and delicacy exalt humanity and make the contingent beings progress. Even when applied to physical things, delicacy causeth the attainment of spirituality, as it is established in the Holy Scriptures.
External cleanliness, although it is but a physical thing, hath a great influence upon spirituality. For example, although sound is but the vibrations of the air which affect the tympanum of the ear, and vibrations of the air are but an accident among the accidents which depend upon the air, consider how much marvelous notes or a charming song influence the spirits! A wonderful song giveth wings to the spirit and filleth the heart with exaltation. To return to the subject, the fact of having a pure and spotless body likewise exerciseth an influence upon the spirit of man.
Now, see how much purity is approved in the Court of God, that it should be especially mentioned in the Holy Books of the Prophets. So the Holy Books forbid the eating of any unclean thing, or the use of anything which is not pure. Certain prohibitions are absolute and imperative for all: he who commits that which is forbidden is detested by God and excluded from the number of the elect. This applieth to the things forbidden by an absolute prohibition and of which the perpetration is a grave sin; they are so vile that even to mention them is shameful. There are other forbidden things which do not cause an immediate evil and of which the pernicious effect is only gradually produced. They are also abhorred, blamed and rejected by God, but their prohibition is not recorded in an absolute way, although cleanliness and sanctity, spotlessness and purity, the preservation of health and independence are required by these interdictions.
One of these last prohibitions is the smoking of tobacco, which is unclean, malodorous, disagreeable and vulgar and of which the gradual harmfulness is universally recognized. All clever physicians have judged, and have also shown by experiment, that one of the constituents of tobacco is a mortal poison and that smokers are exposed to different indispositions and maladies. That is why cleanly people have a marked aversion for its use.
His supreme Highness the Báb -- may my soul be His sacrifice! -- in the beginning of His Cause, openly forbade it and all the friends abandoned its use. But, as it was a time for caution and he who abstained from smoking was ill treated, persecuted and even killed, therefore the friends were obliged, as a matter of prudence, to smoke. Later, the Kitáb-i-Aqdas was revealed and as the prohibition of tobacco was not clearly stated in it, the friends did not renounce it. But the Blessed Perfection had always a marked aversion for its use. At the beginning of the Cause, for certain reasons, He smoked a little, but later He abandoned it completely, and the holy souls who obeyed Him in all circumstances, also entirely gave up smoking. I wish to say that, in the sight of God, the smoking of tobacco is a thing which is blamed and condemned, very unclean, and of which the result is by degrees injurious. Besides it is a cause of expense and of loss of time and it is a harmful habit. So, for those who are firm in the Covenant, it is a thing reprobated by the reason and by tradition, the renouncement of which giveth gradual repose and tranquility, permitteth one to have stainless hands and a clean mouth, and hair which is not pervaded by a bad odor.
Without any doubt, the friends of God on receiving this epistle will renounce this injurious habit by all means, even if it be necessary to do so by degrees. This is my hope.
As to the question of opium, disgusting and execrated, I resign myself to God for its punishment. The formal text of the Kitáb-i-Aqdas forbids and reproves it and, according to reason, its use leads to madness. Experience hath shown that he who giveth himself up to it is completely excluded from the world of humanity. Let us take refuge in God against the perpetration of so shameful a thing, which is the destruction of the foundations of humanity and which causeth a perpetual unhappiness. It taketh possession of the soul of man, killeth the reason, weakeneth the intelligence, maketh a living man dead and extinguisheth the natural heat. It is impossible to imagine anything more pernicious. Happy is he who never mentioneth the word opium! But what is the fate of those who make use of it!
O friends of God! Force and violence, constraint and oppression are condemned in this divine cycle, but to prevent the use of opium, all means must be employed, so that the human species may be delivered and freed from this great calamity. Otherwise, alas! for all the negligent before God.
O Lord! Give to the people of Bahá cleanliness and holiness in all conditions, purify and free them from all defilement, deliver them from the use of all that is execrated, liberate them from the chains of habits, so that they may be pure and free, clean and spotless, that they may be worthy servants of the Sacred Threshold and may deserve to enter into relation with God. Deliver them from alcohol and tobacco, and save them from opium, the purveyor of madness! Make them companions of the holy breezes, in order that they may know the pleasures of the wine of the love of God, and that they may attain to the joy and the happiness of attraction to the Kingdom of Abhá!
Hast Thou not said, "All that thou hast in thy cellar will not appease the thirst of my love -- bring me, O cup-bearer of the wine of the spirit, a cup full as the sea!"
O friends of God! Experience hath shown how much the renouncing of tobacco, wine and opium, giveth health, strength and intellectual enjoyments, penetration of judgment and physical vigor. There exists today a tribe which refrains and abstains from tobacco, alcohol and opium and it completely excels all others in power, in bravery, in health, beauty and grace. A single one of these men can withstand ten men of other tribes, and this hath been universally proved; that is to say, generally, the individuals of this tribe are superior to the individuals of the other tribes.
Therefore strive that the greatest cleanliness and sanctity, which is the great desire of ‘Abdu’l-Bahá, should be resplendent among the Bahá’ís, and that the companions of God should surpass the rest of mankind in all conditions and perfections; that they may be physically and morally superior to others; that through cleanliness and purity, refinement and health, they may be the chief of wise men, and that by their affranchisement, their prudence, and the control of their desires, they may be the princes of the pure, the free and the wise.
