(28) The fifth test is, he will be covetous of retirement and privacy for purposes of devotion; he will long for the approach of night, so that he may hold intercourse with his Friend without let or hindrance. If he prefers conversation by day and sleep at night to such retirement, then his love is imperfect. God said to David, "Be not too intimate with men; for two kinds of persons are excluded from My presence: those who are earnest in seeking reward and slack when they obtain it, and those who prefer their own thoughts to the remembrance of Me. The sign of My displeasure is that I leave such to themselves."

(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:

(12) The Sufi hearer, however, is in danger of blasphemy if he applies some of the verses which he hears to God. For instance, if he hears such a verse as "Thou art changed from thy former inclination," he must not apply it to God, who cannot change, but to himself and his own variations of mood. God is like the sun, which is always shining, but sometimes for us His light is eclipsed by some object which intervenes between us and Him.

(6) But the variety of disposition arises from inordinate affection to material things. And for this reason, as they appear to me, to have called night Euphrone; since then the soul, released from the perceptions of sense, turns in on itself, and has a truer hold of intelligence (Fronhsis). Wherefore the mysteries are for the most part celebrated by night, indicating the withdrawal of the soul from the body, which takes place by night. "Let us not then sleep, as do others; but let us watch and be sober. For they that sleep, sleep in the night; and they that are drunken, are drunken in the night. But let us who are of the day be sober, putting on the breastplate of faith and love, and as an helmet the hope of salvation." And as to what, again, they say of sleep, the very same things are to be understood of death. For each exhibits the departure of the soul, the one more, the other less; as we may also get this in Heraclitus: "Man touches night in himself, when dead and his light quenched; and alive, when he sleeps he touches the dead; and awake, when he shuts his eyes, he touches the sleeper." "For blessed are those that have seen the Lord," according to the apostle; "for it is high time to awake out of sleep. For now is our salvation nearer than when we believed. The night is far spent, the day is at hand. Let us therefore cast off the works of darkness, and put on the armour of light." By day and light he designates figuratively the Son, and by the armour of light metaphorically the promises.
