In Section 2 of the tenth chapter of the Hadiqat al-Haqiqah, Sana'i uses the striking metaphor of pregnancy and childbirth to describe the process of poetic and spiritual composition. He describes his pen (khameh) as being 'pregnant from the heart' (az dil abistan ast), which causes it to crave and 'eat clay' (gol khordan)—a playful reference to the pen touching paper or ink, mimicking a pregnant woman's cravings. Through this imagery, Sana'i portrays the poet's mind and nature as a fertile ground that conceives divine meanings from the spiritual heart, resulting in the birth of refined, 'light-spirited' literary gems (dokhtar-e tab'). This creative pregnancy metaphor contrasts with his negative use of 'eating clay' as worldly attachment elsewhere in the text, highlighting instead the positive, generative aspect of spiritual expression.
