The heart of Rumi’s teaching lies in the Sufi concept of tawhid (or “oneness”). This is a longing for mystical union with the Beloved, with the divine lover from whom one has been separated. In the opening lines of his most famous work, the Masnavi (his “flute songs”), Rumi portrays the soul as a reed cut from the damp reed-bed of God’s own heart. It yearns to return to its source, finding a transient joy in becoming a reed flute through which the divine breath of love’s fire passes. [1] Like a drunken fool, Rumi is smitten by love. He can think of nothing else.
