"The whole year you must fast, just as ordinary Muslims (zahiriyan) fast for one month. The meaning of this fast is austerity. Control yourselves, keep yourselves away from bad qualities, evil and indecent actions and devilish acts, so that the mirror of your hearts may be gradually polished.
 
...—you must be patient, persevering in austerities, and keeping your inner self fasting as long as you live.
 
Here we specify the parts of the fast of the inner self: the fast of the head means to treat one's own head with the same humility as the feet of other people, casting out from one's head the lust of superiority, greatness and pride, because greatness and superiority are only suitable to the all-great substance of the Truth (Haqq), who is eternal, the King of the Authority.
 
The fasting of the eye means that one must keep away coveting looks from the women who are not lawful to one. The fasting of the ear means that one should abstain from listening to slander. The fasting of the tongue means that one should keep one's tongue from uttering abuse or slander. The fasting of the heart means to keep the heart free from doubt. The fasting of the foot is to hold one's foot back from a wrong step. The fasting of the hand is to keep all one's limbs away from treachery so that they may not do evil. This especially applies to one's tongue which must be kept from uttering lies. And there is no greater lie than the denial of (the existence of) the Imam, saying that he has disappeared. God has cursed liers, who talk about such a disappearance (of the Imam), and make the ignorant people follow them in order to enjoy their short lived respect."
