As regards fasting, it constitutes, together with the obligatory prayers, the two pillars that sustain the revealed Law of God. They act as stimulants to the soul, strengthen, revive and purify it, and thus insure its steady development.
The ordinance of fasting is, as is the case with these three prayers (obligatory) a spiritual and vital obligation enjoined by Bahá’u’lláh upon every believer who has attained the age of fifteen. In the Aqdas He thus writes: ‘We have commanded you to pray and fast from the beginning of maturity; this is ordained by God, your Lord and the Lord of your forefathers. He has exempted from this those who are weak from illness or age, as a bounty from His Presence, and He is the Forgiving, the Generous.’
And in another passage He says: ‘We have enjoined upon you fasting during a brief period, and at its close have designated for you Naw-Rúz as a Feast… The traveller, the ailing, those who are with child or giving suck, are not bound by the Fast… Abstain from food and drink, from sunrise to sundown, and beware lest desire deprive you of this grace that is appointed in the Book.’
Also in the ‘Questions and Answers’ that form an appendix to the Aqdas, Bahá’u’lláh reveals the following: ‘Verily, I say that God has appointed a Great station for fasting and prayer. But during good health its benefit is evident, and when one is ill, it is not permissible to fulfill them.’ Concerning the age of maturity, He reveals in the appendix of that same Book: ‘The age of maturity is in the fifteenth year; women and men are alike in this respect.’ Regarding the vital character and importance of the Divine ordinances and laws, and the necessity of complete obedience to them by the believers, we thus read in the Gleanings, p. 175:
‘Know verily that the essence of justice and the source thereof are both embodied in the ordinance prescribed by Him Who is the Manifestation of the Self of God amongst men, if ye be of them that recognize this truth. He doth verily incarnate the highest, the infallible standard of justice unto all creation. Were His law to be such as to strike terror in the hearts of all that are in heaven and on earth, that law is naught but manifest justice. The fears and agitation which the revelation of this law provoke in men’s hearts should indeed be likened to the cries of the suckling babe weaned from his mother’s milk, if ye be of them that perceive…’
Shoghi Effendi, Directives of the Guardian, containing quotes from Baha’u’llah
Happy is your condition for you have executed the divine command; and have arisen to fast in these blessed days. For this physical fasting is a symbol of the spiritual fasting, that is, abstaining from all carnal desires, becoming characterized with the attributes of the spiritual ones, attracted to the heavenly fragrances and enkindled with the fire of the love of God.
Abdu’l-Baha’, Tablets
Prayer
Praise be to Thee, O Lord my God! I beseech Thee by this Revelation whereby darkness hath been turned into light, through which the Frequented Fane hath been built, and the Written Tablet revealed, and the Outspread Roll uncovered, to send down upon me and upon them who are in my company that which will enable us to soar into the heavens of Thy transcendent glory, and will wash us from the stain of such doubts as have hindered the suspicious from entering into the tabernacle of Thy unity.
I am the one, O my Lord, who hath held fast the cord of Thy loving-kindness, and clung to the hem of Thy mercy and favors. Do Thou ordain for me and for my loved ones the good of this world and of the world to come. Supply them, then, with the Hidden Gift Thou didst ordain for the choicest among Thy creatures.
These are, O my Lord, the days in which Thou hast bidden Thy servants to observe the fast. Blessed is he that observeth the fast wholly for Thy sake and with absolute detachment from all things except Thee. Assist me and assist them, O my Lord, to obey Thee and to keep Thy precepts. Thou, verily, hast power to do what Thou choosest.
There is no God but Thee, the All-Knowing, the All-Wise. All praise be to God, the Lord of all worlds.
Baha’u’llah
