The Kitáb-i-Aqdas - The Most Holy Book
Index term: Wine
k4.
Say: From My laws the sweet-smelling savour of My garment can be smelled, and by their aid the standards of Victory will be planted upon the highest peaks. The Tongue of My power hath, from the heaven of My omnipotent glory, addressed to My creation these words: "Observe My commandments, for the love of My beauty." Happy is the lover that hath inhaled the divine fragrance of his Best-Beloved from these words, laden with the perfume of a grace which no tongue can describe. By My life! He who hath drunk the choice wine of fairness from the hands of My bountiful favour will circle around My commandments that shine above the Dayspring of My creation.
k5.
Think not that We have revealed unto you a mere code of laws. Nay, rather, We have unsealed the choice Wine with the fingers of might and power. To this beareth witness that which the Pen of Revelation hath revealed. Meditate upon this, O men of insight!
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.
k173.
Happy are ye, O ye the learned ones in Bahá. By the Lord! Ye are the billows of the Most Mighty Ocean, the stars of the firmament of Glory, the standards of triumph waving betwixt earth and heaven. Ye are the manifestations of steadfastness amidst men and the daysprings of Divine Utterance to all that dwell on earth. Well is it with him that turneth unto you, and woe betide the froward. This day, it behoveth whoso hath quaffed the Mystic Wine of everlasting life from the Hands of the loving-kindness of the Lord his God, the Merciful, to pulsate even as the throbbing artery in the body of mankind, that through him may be quickened the world and every crumbling bone.
n2.
We have unsealed the choice Wine with the fingers of might and power.
The consumption of wine and other intoxicants is prohibited in the Kitáb-i-Aqdas (see notes 144 and 170).
Reference to the use of "wine" in an allegorical sense -- such as being the cause of spiritual ecstasy -- is found, not only in the Revelation of Bahá'u'lláh, but in the Bible, in the Qur'án, and in ancient Hindu traditions.
For example, in the Qur'án the righteous are promised that they will be given to drink of the "choice sealed wine". In His Tablets, Bahá'u'lláh identifies the "choice Wine" with His Revelation whose "musk-laden fragrance" has been wafted "upon all created things". He states that He has "unsealed" this "Wine", thereby disclosing spiritual truths that were hitherto unknown, and enabling those who quaff thereof to "discern the splendours of the light of divine unity" and to "grasp the essential purpose underlying the Scriptures of God". In one of His meditations, Bahá'u'lláh entreats God to supply the believers with "the choice Wine of Thy mercy, that it may cause them to be forgetful of any one except Thee, and to arise to serve Thy Cause, and to be steadfast in their love for Thee".
n144.
It is inadmissible that man, who hath been endowed with reason, should consume that which stealeth it away.
There are many references in the Bahá'í Writings which prohibit the use of wine and other intoxicating drinks and which describe the deleterious effect of such intoxicants on the individual. In one of His Tablets, Bahá'u'lláh states:

Beware lest ye exchange the Wine of God for your own wine, for it will stupefy your minds, and turn your faces away from the Countenance of God, the All-Glorious, the Peerless, the Inaccessible. Approach it not, for it hath been forbidden unto you by the behest of God, the Exalted, the Almighty.

'Abdu'l-Bahá explains that the Aqdas prohibits "both light and strong drinks", and He states that the reason for prohibiting the use of alcoholic drinks is because "alcohol leadeth the mind astray and causeth the weakening of the body".
Shoghi Effendi, in letters written on his behalf, states that this prohibition includes not only the consumption of wine but of "everything that deranges the mind", and he clarifies that the use of alcohol is permitted only when it constitutes part of a medical treatment which is implemented "under the advice of a competent and conscientious physician, who may have to prescribe it for the cure of some special ailment".
