“Nor did he find light in philosophy, although he thoroughly studied the various systems of his day and refuted them. Religion is not merely of the mind but of the heart; philosophy had its place but could satisfy only the intellect and left the deepest longings of the soul unsatisfied. Next he examined the teachings of the Taʾlimites, the contemporary sect of the Ishmaelites founded by Hassan Ibn as Sabbah. Theirs was the doctrine of an Imam or infallible spiritual guide and the sect found large following. But Al-Ghazali, so far from being attracted by them, wrote several books against them.”[35] No other path remained open for the perplexed and sceptical seeker after God than the way of the mystics. It was a return to the early teaching he received at Tus and Nishapur and to the atmosphere of his native land which was for centuries steeped in mysticism. Of this period of his life he was wont to say:

“When I wished to plunge into following the people and to drink of their drink, I looked at my soul and I saw how much it was curtained in, so I retired into solitude and busied myself with religious exercises for forty days, and there was doled to me of knowledge I had not had purer and finer than what I had known. Then I looked upon it, and lo, in it was a legal element. So I returned to solitude and busied myself with religious exercises for forty days, and there was doled to me other knowledge, purer and finer than what had befallen me at first, and I rejoiced in it. Then I looked upon it, and lo, in it was a speculative element. So I returned to solitude a third time for forty days, and there was doled to me other knowledge that is known (i. e., not simply perceived, felt), and I did not attain to the people of the inward sciences. So I know that writing on a surface from which something has been erased is not like writing on a surface in its first purity and cleanness, and I never separated myself from speculation except in a few things.”

Who can read this and doubt his utter sincerity in the search for God and for Truth?

He tells the rest of the story in his “Confessions”: “I saw that Sufism consists in experiences rather than in definitions, and that what I was lacking belonged to the domain, not of instruction but of ecstasy and initiation.

“The researches to which I had devoted myself, the path which I had traversed in studying religious and speculative branches of knowledge, had given me a firm faith in three things—God, inspiration, and the Last Judgment. These three fundamental articles of belief were confirmed in me, not merely by definite arguments, but by a chain of causes, circumstances, and proofs which it is impossible to recount. I saw that one can only hope for salvation by devotion and the conquest of one’s passions, a procedure which presupposes renouncement and detachment from this world of falsehood in order to turn towards eternity and meditation on God. Finally, I saw that the only condition of success was to sacrifice honours and riches and to sever the ties and attachments of worldly life.

“Coming seriously to consider my state, I found myself bound down on all sides by these trammels. Examining my actions, the most fair-seeming of which were my lecturing and professorial occupations, I found to my surprise that I was engrossed in several studies of little value, and profitless as regards my salvation. I probed the motives of my teaching and found that, in place of being sincerely consecrated to God, it was only actuated by a vain desire of honour and reputation. I perceived that I was on the edge of an abyss, and that without an immediate conversion I should be doomed to eternal fire. In these reflections I spent a long time. Still a prey to uncertainty, one day I decided to leave Bagdad and to give up everything; the next day I gave up my resolution. I advanced one step and immediately relapsed. In the morning I was sincerely resolved only to occupy myself with the future life; in the evening a crowd of carnal thoughts assailed and dispersed my resolutions. On the one side the world kept me bound to my post in the chains of covetousness, on the other side the voice of religion cried to me: ‘Up, Up, thy life is nearing its end, and thou hast a long journey to make. All thy pretended knowledge is nought but falsehood and fantasy. If thou dost not think now of thy salvation, when wilt thou think of it? If thou dost not break thy chains to-day, when wilt thou break them?’ Then my resolve was strengthened, I wished to give up all and flee; but the Tempter returning to the attack said: ‘You are suffering from a transitory feeling; don’t give way to it, for it will soon pass. If you obey it, if you give up this fine position, this honourable post exempt from trouble and rivalry, this seat of authority safe from attack you will regret it later on without being able to recover it.’

“Thus I remained, torn asunder by the opposite forces of earthly passions and religious aspirations, for about six months from the month Rajab of the year A. D. 1096. At the close of them my will yielded and I gave myself up to destiny. God caused an impediment to chain my tongue and prevented me from lecturing. Vainly I desired, in the interest of my pupils, to go on with my teaching, but my mouth became dumb.

“The enfeeblement of my physical powers was such that the doctors despairing of saving me, said: ‘The mischief is in the heart, and has communicated itself to the whole organism; there is no hope unless the cause of his grievous sadness be arrested.’

“Finally, conscious of my weakness and the prostration of my soul, I took refuge in God as a man at the end of himself and without resources. ‘He who hears the wretched when they cry’ (Koran, xxviii. 63) deigned to hear me; He made easy to me the sacrifice of honours, wealth, and family” (“The Confessions,” pp. 42-45).

That his conversion did not mean ethically all that the word means in the Christian sense is evident from what immediately follows. He dissembled: “I gave out publicly that I intended to make the pilgrimage to Mecca, while I secretly resolved to go to Syria, not wishing that the Caliph (may God magnify him) or my friends should know my intention of settling in that country. I made all kinds of clever excuses for leaving Bagdad with the fixed intention of not returning thither. The Imams of Irak criticized me with one accord. Not one of them would admit that this sacrifice had a religious motive, because they considered my position as the highest attainable in the religious community. ‘Behold how far their knowledge goes’ (Koran, liii. 31). All kinds of explanations of my conduct were forthcoming. Those who were outside the limits of Irak attributed it to the fear with which the Government inspired me. Those who were on the spot and saw how the authorities wished to detain me, their displeasure at my resolution and my refusal of their request, said to themselves, ‘It is a calamity which one can only impute to a fate which has befallen the Faithful and Learning.’
