Charkh
The revolving sky, the wheeling heavens; figuratively fate and the turning fortune.
Literally: Persian charkh: a wheel, the revolving celestial sphere.
Charkh is the 'wheel' — the revolving sky imagined as a great turning wheel of fate, classical emblem of the heavens that spin out fortune and misfortune, the 'charkh-e-kaj-raftaar,' the crookedly-turning wheel blamed for the lover's woes. It is cosmic destiny felt as machinery. Iqbal uses the turning wheel as the very image of a determinism the empowered self must rise above, refusing to be ground by the heavens and bidding the believer master the wheel rather than be mastered by it.

Mashriq se ubharte hue suraj ko zara dekh
Falak jis tarah aankh ke til mein hai
Pahunchenge falak tak teri aahon ke sharare
