In Chapter 18, Poem 41 of Attar's Mokhtar Nameh, the poet utilizes the language of commerce (capital, profit, and loss) to articulate a fundamental Sufi principle: spiritual salvation and true "profit" require the complete loss of one's worldly existence. The poem argues that the "capital of life" (one's ego and mortal existence) is essentially useless in the spiritual path unless it is spent or "lost." By urging the seeker to "die in love," Attar underscores the paradox of mystical annihilation (fana): one can only gain the ultimate reward of divine union by first losing oneself entirely.
