In Chapter 8, Poem 15 of Attar's Mokhtar Nameh, the poet explores the mystical necessity of transcending emotional dualities, specifically the joy of union and the grief of separation. Attar advises the spiritual seeker to pass beyond these fluctuating states, which still tie the soul to the realm of self and conditionality.

The core paradox of the poem is the instruction to "content yourself with nothing" (هیچ) in order to attain "the All" (همه). This emphasizes that true spiritual fulfillment and union with the Divine requires complete detachment and self-annihilation (fana), stripping away all worldly and emotional attachments to realize the ultimate, unconditioned reality.
