In Section 18 of the Khosrow Nameh, Farid al-Din Attar employs the metaphor of a sweet-singing ringdove (qomri) to represent the human soul. Attar urges the soul to free itself from the 'debris of the world' (khashak-e donya), which is gathered through the deceptive channels of the five senses. Instead of building a temporary nest in the earthly dust, the soul is encouraged to ascend from the treacherous prison of material existence to its true spiritual home, symbolized by the celestial Tuba tree in Paradise. This passage underscores the Sufi journey of self-transcendence, urging the seeker to look beyond sensory distractions and direct their devotion toward the divine beloved.
