This beyt is discussed directly as part of a series of poetic examples. Dr. Soroush cites it to elaborate on the metaphor of the "reed" (nay) and the concept of humanity's existential "hollowness" (tukhāli būdan) [d1-s4]. Just as the reed produces no sound of its own but is played by the musician, and a mountain merely echoes a sound, we are like chess pieces on a board. Our movements and the outcome of the game—our "wins and checkmates" (bord o māt)—do not originate from us but from the Player, whom Rumi addresses as "O You of beautiful attributes."
This metaphor, alongside others the scholar quotes (such as "We are all lions, but lions on a flag / Their charge is from the wind, moment by moment"), serves to illustrate a foundational concept in Rumi's thought: tawhid-e af'ali, or the unity of actions. According to this view, there is only one true Agent in the universe, and all our actions ultimately derive from the Divine will. We are not the true agents in this game but instruments in the hands of the Absolute Agent. The verse is thus not merely a poetic simile but an expression of a profound mystical principle concerning the relationship between the human and the Divine.
