Sufism, the Religion of the Heart
The word Sufi means wisdom, but that does not mean that when pursuing the Sufi path one is necessarily wise. Sufism is a test with which one is constantly confronted, when expected to show an example of how well one understands what spirituality truly is. Spirituality does not mean drifting away upon the clouds of illusion; it means having the feet firmly on the ground of reality, proving thereby, without pretence to have acquired discipline over the physical and mental energies. It is only then that one can possibly inspire others on the path where honesty in spirituality is the watchword.
