Unity of God, brotherhood of man and self-surrender to the Lord are the most vital doctrines of Sufism. In Sufism God has form. The Sufis recognise His formless aspect too. A Sufi wants to remain in the world and serve humanity, but to be above worldliness. The Sufi language of ecstasy describes the divine experience in a variety of ways such as sweetness, intoxication, perfume, sleep and death.
Wine is a symbol of divine intoxication.
In Sufism, Beauty leads to Love and Love to Bliss. All duality melts. The Lover and the Beloved become one. The Sufi strives to attain Absolute Beauty, Absolute Love and Absolute Bliss. For a Sufi, music is a means to ecstasy.
