In Jalaluddin Rumi's Masnavi, the vizier's physical self-mutilation—severing his own ear and nose to deceive the Christians—is used as an allegory for the destructive consequences of envy and ingratitude. Rumi posits that a "true nose" is not merely a physical organ, but the spiritual faculty capable of catching the "scent" of divine truth and guiding the soul. Because the vizier acted out of profound envy and failed to show gratitude for the spiritual scent he had received, his ingratitude effectively "consumed his nose," leaving him spiritually "noseless" and unable to perceive the truth. Rumi warns that allowing envy to drive one's actions destroys one's spiritual senses. The vizier, posing as a pious religious guide, maliciously mixed "garlic into the almond-sweetmeat," illustrating how envy can masquerade as religious devotion while actually drawing people away from sincere prayer.
