In Chapter 41, Poem 20 of Attar's Mokhtar Nameh, the poet presents the "heart" (دل) and "soul" (جان) as the essential elements for profound existential and spiritual experiences. The poem asserts that whether one seeks the courage for battle, the devotion of a peerless lover, the spiritual yearning associated with the Kaaba, or the transformative pain directed toward the Qibla, the heart and soul are the ultimate requisites. This highlights the central role of inner spiritual faculties in Sufi philosophy, serving as the locus for love, courage, yearning, and divine pain.
