In Chapter 26, Poem 16 of Attar's Mokhtar Nameh, the poet explores the profound spiritual role of sorrow in the pursuit of divine love. The poem asserts that the "torrent" arising from the "blood of the heart"—symbolizing deep spiritual anguish and longing—acts as a true guide in the "valley of love." In contrast, any happiness rooted in "illusion" or worldly attachment is ephemeral and ultimately leads to weeping. This reflects a core Sufi theme where enduring the painful yearning of love is essential for spiritual awakening, while superficial joys are deceptive and fleeting.
