In Chapter 13, Poem 18 of Attar's Mokhtar Nameh, the poet explores the theme of spiritual capacity and its divine origin. The speaker acknowledges that their soul is completely submerged in the divine ocean, possessing no inherent capacity for the spiritual journey. Instead, any capacity, endurance, or ability to undertake spiritual work is entirely bestowed by the passion and love for the Beloved. This highlights the Sufi concept that spiritual progress relies not on individual merit or innate human ability, but on the transformative power and grace of divine love.
