Sufism has helped to shape large parts of Muslim society. The orthodox disagree with such aspects of Sufism as saint worship, visiting of tombs, musical performances, miracle mongering, degeneration into jugglery, and the adaptation of pre-Islamic and un-Islamic customs; and the reformers object to the influences of the monistic interpretation of Islam upon moral life and human activities. The importance given to the figure of the master is accused of yielding negative results; the shaykh as the almost infallible leader of his disciples and admirers could gain dangerous authority and political influence, for the illiterate villagers in backward areas used to rely completely upon the "saint." Yet, other masters have raised their voices against social inequality and have tried, even at the cost of their lives, to change social and political conditions for the better and to spiritually revive the masses. The missionary activities of the Sufis have enlarged the fold of the faithful. The importance of Sufism for spiritual education, and inculcation in the faithful of the virtues of trust in God, piety, faith in God's love, and veneration of the Prophet, cannot be overrated. The dhikr formulas still preserve their consoling and quieting power even for the illiterate. Mysticism permeates Persian literature and other literatures influenced by it. Such poetry has always been a source of happiness for millions, although some modernists have disdained its "narcotic" influence on Muslim thinking.
Industrialization and modern life have led to a constant decrease in the influence of Sufi orders in many countries. The spiritual heritage is preserved by individuals who sometimes try to show that mystical experience conforms to modern science. Today in the West, Sufism is popularized, but the genuinely and authentically devout are aware that it requires strict discipline, and that its goal can be reached--if at all--as they say, only by throwing oneself into the consuming fire of divine love.
