In Chapter 23, Poem 37 of the Mokhtar Nameh, Attar explores the themes of aging, the physical toll of lifelong spiritual struggle (jihad al-nafs), and the inevitability of decline.

Key Concepts:

1. Lifelong Spiritual Combat: The poet reflects on fifty years of active struggle against the self (khwishtan), representing a lifetime of spiritual striving and self-mortification.
2. The Inevitability of Old Age: Reaching sixty years represents a major turning point where time asserts control over the lifespan.
3. The Bow Metaphor: Attar employs a classic Persian literary pun on the word shast (meaning both 'sixty' and 'thumb/bowstring/bow'). Upon completing sixty years, the back inevitably bends like a bow (kaman), symbolizing physical stooping and vulnerability at the end of life.
