"The believer must keep pure and clean both in his body and soul (zahir wa batin). He must keep clean his dress, body, and heart, in order that angels may accompany him. Because if his body and soul are defiled and if he does not keep them clean, his associate and the one who shares his bed with him will be diws and devils. They also will take their place in his heart. Therefore you must observe (ritual) purity (taharat). Just as the zahiris for their zahiri worship do their ritual ablutions (taharat) and wudu so the internal ablution is the washing in truth (wudu-i haqiqi) which is necessary for the soul,—let the followers of the truth (ahl-i haqiqat) know this and follow this rule.
 
The ablution of the head means to keep oneself obedient to the Imam. The ablution of the hand is swearing allegiance (bay'at dadan) to the Imam of the time. The ablution of the foot is to advance along Imam's way in obedience to him. The ablution of the heart is to keep steady in affection for the Imam. The ablution of the tongue is to keep on continually remembering (dhikr) the Imam. The ablution of the eye is to have the chance of the didar of the Imam of the time.
 
The one who obeys the orders and words of the Imam has all his limbs purified, and he who has found the way to the Imam, and resigned himself in the obedience of his command,—his soul becomes clean, and his spirit good. But if one knows nothing of the Imam, or denies his existence, or does not accept the Imamat of the Imam, or nourishes doubt as to his Imamat, he will become like the one who is continuously in a state of ritual uncleanliness. Therefore seek refuge with God from those who do not accept this, and believe in shari'at which has reduced (cleanliness) to those outer ablutions while overlooking the inner self. For both the body and the soul must be purified."
