In Chapter 4, Poem 93 of Attar's Mokhtar Nameh, the speaker exalts the grief of divine love as a priceless treasure, declaring it too precious to be exchanged for one's life or the entirety of both worlds. The poem further uses the metaphor of a desert to describe the journey of love, asserting that any heart that enters this vast wilderness is permanently lost without a trace. This illustrates the mystic principles of the supreme worth of spiritual suffering and the ultimate annihilation (Fana) of the self in the Divine.
