And He it is who created night and day, and the sun and the moon, each swimming in a sphere. In the tasting of the folk of recognition, night and day are a mark of the contraction and expansion of the recognizers. Contraction and expansion are the divine decree and royal predetermination. Sometimes He puts them in the grasp of His contraction so that the ruling power of His majesty [wreaks havoc on them, and sometimes He gives them a place on the carpet of His expansion such that the ruling power of beauty] may caress them in virtue of bestowal. It is the stipulation of the man with pain that in the grasp of contraction he be rectified and not protest, and on the carpet of expansion he be courteous and not turn away, for the great ones of the religion have said, “The servant will not find the sweetness of faith until trial comes to him from everywhere.” And the sun and the moon, each swimming in a sphere. He created the sun and the moon in the constellations of heaven, and they travel on the peak of the spheres. He created the sun neither to increase nor to decrease and the moon to increase and decrease; sometimes it wanes, and some- times it shines forth. The sun is the mark of the possessor of tawḤīd, who says with the attribute of stability in the presence of stability, “Were the covering to be lifted, I would not increase in certainty.” The moon is the mark of the possessor of knowledge, who walks in the playing field of exertion. He comes by way of gazing and inference and keeps his eyes on obedience and good works, that they might add faith to their faith [48:4]. The possessor of tawḤīd is the lord of pain, and the possessor of knowledge is the lord of deeds. The possessor of deeds gazes on the secondary causes, and the possessor of pain gazes on the Causer and is detached from the secondary causes. The great ones of the religion have said, “Not seeing the secondary cause is ignorance, but remaining with the secondary cause is associationism.” A recognizer was seen on the shore of the Tigris, saying, “My Master, I am thirsty,” but he passed by without drinking. That exalted man was contemplating the Real and saw neither the Tigris nor its water. When someone is busy with a work, even if the houris of paradise pass by, he will not be aware. God only knows, sweetheart, if I know night from day- night and day passion has confounded and perplexed me.
