“Single-minded monists, ruthless fanatics, men possessed by an all-embracing coherent vision do not know the doubts and agonies of those who cannot wholly blind themselves to reality.”

As quoted in "Husayn ibn Mansur al-Hallaj" at Sidi Muhammad Press http://www.sufimaster.org/teachings/husayn.htm
Context: Love is in the pleasure of possession, but in the Love of Allah there is no pleasure of possession, because the stations of the Reality are wonderment, the cancelling of the debt which is owed, and the blinding of vision. The Love of the human being for God is a reverence which penetrates the very depths of his being, and which is not permitted to be given except to Allah alone. The Love of Allah for the human being is that He Himself gives proof of Himself, not revealing Himself to anything that is not He.

Context: We hear often of the distress of the negro servants, on the loss of a kind master; and with good reason, for no creature on God's earth is left more utterly unprotected and desolate than the slave in these circumstances.
The child who has lost a father has still the protection of friends, and of the law; he is something, and can do something, — has acknowledged rights and position; the slave has none. The law regards him, in every respect, as devoid of rights as a bale of merchandise. The only possible acknowledgment of any of the longings and wants of a human and immortal creature, which are given to him, comes to him through the sovereign and irresponsible will of his master; and when that master is stricken down, nothing remains.
The number of those men who know how to use wholly irresponsible power humanely and generously is small. Everybody knows this, and the slave knows it best of all; so that he feels that there are ten chances of his finding an abusive and tyrannical master, to one of his finding a considerate and kind one. Therefore is it that the wail over a kind master is loud and long, as well it may be.

Context: I am well aware of how anarchic much of what I say may sound. Expressing myself thus abstractly and briefly, I may seem to despair of the very notion of truth. But I beseech you to reserve your judgment until we see it applied to the details which lie before us. I do indeed disbelieve that we or any other mortal men can attain on a given day to absolutely incorrigible and unimprovable truth about such matters of fact as those with which religions deal. But I reject this dogmatic ideal not out of a perverse delight in intellectual instability. I am no lover of disorder and doubt as such. Rather do I fear to lose truth by this pretension to possess it already wholly.

Context: "The perfect ghost story is the story of Possession," he said, "and that is hypnotism from beyond the grave. This is possible since hypnotism is by the will, and the will is immortal. A number of notable men have been possessed, and all of their lives seem to fit a pattern: the inconsequential early years, the hiatus when they stood where Faust stood, and the decision. And then the rise to power and influence and almost universal honor after they have made the deal. But it is not themselves, it is the devils within them that gain these things. They are the possessed men who do much of the running of the world, and theirs is the most frightening story that can be imagined. But those who watch the great men do not know that they are shells inhabited by ghosts."
