Ghazzali’s abandonment of his academic position at Baghdad, his retirement to mosques and journeyings on pilgrimage, are sufficient evidence that he recognised that the truth of mysticism could not be tested by theoretical reflection but only by an attempt at practice. Only the experience itself could prove its own reality. He appears to have held that for the attainment of the condition of ecstasy the means of asceticism and meditation should be used. But it does not seem quite correct to suggest as does Carra de Vaux that Ghazzali did not recognise the fact of divine “grace”, though he did not use a corresponding term. The beatific vision of the mystic certainly depended in part, for Ghazzali, on God’s mercy in removing the veil. How far he himself was successful in attaining the bliss of the mystic vision it is impossible to tell: in this direction he gained no such reputation as did several other Sufis. He taught that repentance, a moral conversion, is a necessary preliminary to the mystic life, and he fought against a common tendency of mystics towards antinomianism. Similarly he tried to avoid the danger of interpreting the union of the soul with God as its identification with God in a pantheistic view of the universe. Goldzieher says he differed from the Sufis generally in the rejection of their pantheistic aims and low estimate of religious ordinances.[10] A LIST OF WORKS BY AL GHAZZALI[11] A: CANON LAW. _Title._ _Subject._ _Place and date of publication._ _K.
