It requires extra hard practice...
It requires extra hard practice, going to some lengths, spiritual exercises, perseverance, and discipline, until one is able to fix one’s attention completely on nothing but God and cut himself off from all else. If someone is able to do this, he has reached a great felicity. However, with the least attention to this world it is impossible to be cut off from all else but Allah.
Someone who wants to perform the fast of the blessed month of Ramadan with such manners as he has been asked to, must cut himself off completely from all else so that he can observe the manners for the celebration and feast [of Allah], coming to know of the station of the Host, insofar as this is possible.
According to the order of the Holy Apostle, peace be upon him and his progeny, (which is related in one of his sermons) all of the servants of God, the Supreme, have been invited by Him to a feast in the blessed month of Ramadan and are to be the guests of the Provider at His feast. He says there: “O you people!
The month of Allah is approaching you…and you have been invited in it to the feast of Allah.” [^3] In this few days until the blessed month of Ramadan, you should reflect, reform yourselves, and pay attention to God Almighty, seek forgiveness for your unbecoming behavior and deeds, and if, God forbid, you have committed a sin, repent for it prior to entering the blessed month of Ramadan. Habituate your tongue to intimate devotions [ munajat ] to God the Almighty.
God forbid that in the blessed month of Ramadan you should backbite or slander, or in short, sin, and so become polluted by transgression in the presence of the Lord, the Exalted, at His feast. You have been invited during this honorable month to the banquet of God the Almighty, “and you have been invited in it to the feast of Allah,” so, get yourself ready for the magnificent feast of the Almighty. At least respect the formal and exoteric manners of fasting.
(The true manners of fasting are another matter entirely, and require constant care and effort.) The meaning of fasting is not merely refraining from eating and drinking, one must also keep oneself from sin. This is the primary etiquette of fasting for novices.
(The etiquette of fasting for divine people who want to reach the mine of greatness is other than this.) You should at least observe the primary etiquette of fasting, and in the same way that you refrain from eating and drinking, you should keep your eyes, ears and tongue from transgression.
