Ibn Arabi was a prominent 12th-century Islamic philosopher, mystic, and poet from Spain. Known as the "Greatest Master," he significantly influenced Sufism, the mystical branch of Islam. His works explore the nature of God, the universe, and the human soul, emphasizing the concept of unity in diversity. His most famous work, The Meccan Revelations, presents his spiritual insights and experiences. Ibn Arabi's ideas on wahdat al-wujud (the unity of existence) have inspired countless scholars and spiritual seekers, making him a central figure in Islamic thought and mysticism.
