Sufis, instead of teaching the lesson of indifference, have taught the lesson of love and sympathy, and have called it the cultivation of the heart. In Sufi terminology this is called Suluk, which means the divine manner, the loving manner. When a refined manner is directed by the heart quality, it becomes a loving manner, the manner of God, and all such attributes as gentleness, tolerance, kindness, forgiveness, mercy, and compassion spring from it.
