In Section 131 of Jami's Haft Awrang (specifically in Silsilat al-Dhahab), hunger (ju') is established as the third pillar of walayah (sainthood or spiritual guardianship). Jami defines hunger as the spiritual nourishment of the pure (ghiza-ye ahl-e safa). Referencing the Prophetic tradition that Satan flows through human veins like blood, Jami explains that voluntary hunger narrows these internal passages, thereby constraining Satanic temptation. Conversely, satiety is depicted as a state that leads the bodily limbs to commit sins, establishing hunger as a crucial spiritual asset (ra's al-mal) for mystical progression.
