Sholah
A flame or blaze; figuratively burning intensity.
Literally: flame, blaze
Sho'la is the leaping flame — the visible fire of passion, taller and more dramatic than the spark, the blaze of a heart fully alight with love or longing. The ghazal makes it an image of beauty (the beloved's face like a flame) and of the lover's own burning. In Iqbal's symbolism the sho'la is the restless upward-striving of the living self, fire that refuses to lie still — the flame as the very emblem of a soul that will not be content.
