This article is from Purification of the Mind (Jila’ Al-Khatir)
* If the truthful person meets all creatures he would not like to look at anyone other than his Beloved. This world does not seem significant to the eyes of his head, the hereafter does not seem significant to the eyes of his heart, and nothing seems significant to the eyes of his innermost being other than the Master. The shouting of the hypocrite comes from his tongue and head, whereas the shouting of the truthful person springs from his heart and innermost being. His heart is at the door of his Lord (mighty and glorified is He) and his innermost being has entered into His presence. It keeps on shouting at the door until it enters the house.
* O liars, the truthful person never tells lies. The truthful person never turns back! The truthful person has no back. He is a front with no back, truthfulness with no telling of lies. He is words and action, claim and evidence. He never turns back from his Beloved because of arrows that come to him from Him, but he rather receives them with his breast. Your love for something blinds and deafens you. When one knows what he is seeking, he sees whatever he has to do to be as insignificant. The lover who is truthful in his love always plunges into dangers in the quest for his Beloved. If he faces an inferno, he throws himself right into it. He swoops at what others would not even dare approaching. It is his truthfulness that urges him to do this. It is his love and impatience with being distant from his Beloved that make behave like this. Afflictions reveal the truthful person and the liar and distinguish between them. How excellent this piece of poetry by one of them is:
It is at times of dissatisfaction not at times of satisfaction
that the lover becomes identifiable from the hater.1
