(8) As regards the erotic poetry which is recited in Sufi gatherings, and to which people sometimes make objection, we must remember that, when in such poetry mention is made of separation from or union with the beloved, the Sufi, who is an adept in the love of God, applies such expressions to separation from or union with Him. Similarly, "dark locks" are taken to signify the darkness of unbelief; "the brightness of the face," the light of faith, and "drunkenness" the Sufi's ecstasy. Take, for instance, the verse:

(29) In truth, if the love of God really takes possession of the heart all other love is excluded. One of the Children of Israel was in the habit of praying at night, but, observing that a bird sang in a certain tree very sweetly, he began to pray under that tree, in order to have the pleasure of listening to the bird. God told David to go and say to him, "Thou hast mingled the love of a melodious bird with the love of Me; thy rank among the saints is lowered." On the other band, some have loved God with such intensity that, while they were engaged in devotion, their houses have caught fire and they have not noticed it.
