This concept explores the central theme in Attar's Mokhtar Nameh, Chapter 4, Poem 65, where enduring grief (غم) is presented as a transformative and refining process for the human soul. The poem advises against despairing over the 'hundred colors' (صد رنگ) or multifaceted afflictions of the material world. Instead, it suggests that patiently bearing this spiritual distress eventually leads to a state of ultimate unity and transcendence, where everything becomes 'of one color' (یک رنگ), symbolizing union with the divine and the dissolution of worldly multiplicities.
