The symbol of the Sufi Order is a heart with wings. It explains that the heart is between soul and body, a medium between spirit and matter. When the soul is covered by its love for matter, it is naturally attracted to matter. This is the law of gravitation in abstract form, as it is said in the Bible, ‘Where your treasure is, there will your heart be also.’ When man treasures the things of the earth, his heart is drawn to the earth. But the heart is subject not only to gravitation, but also to attraction from on high, and as in the Egyptian symbology wings are the symbol of spiritual progress, so the heart with wings expresses that the heart reaches upward towards heaven.
