In Chapter 19, Poem 4 of Attar's Mokhtar Nameh, the poet emphasizes the absolute exclusivity of the human heart for the Divine. The poem warns that whatever takes root in the seeker's heart inevitably usurps God's rightful place. It suggests that true spiritual devotion requires emptying the heart of all 'others' so that only the Divine remains, highlighting the incompatibility of divine presence with worldly or secondary attachments.
