In Chapter 41, Poem 13 of Attar's Mokhtar Nameh, the poet explores the intricate dynamics of mystical longing and suffering. The poem presents two key Sufi concepts:

1. The Unlost Secret: The heart reveals its spiritual secret through the eye (representing tears of yearning), seeking a Divine presence that was never actually lost. This reflects the mystical idea that the Beloved is ever-present, yet the seeker must still experience the painful journey of longing to realize it.
2. The Paradox of Divine Pain: The lover uses the pain of separation as a 'balm of patience.' However, enduring this pain only washes over them with a new wave of spiritual suffering from the Beloved, illustrating the endless, agonizing, yet purifying nature of the mystical path.
