Do not judge the brilliance of this inherent quality by the glamour of a foreign light, for its brilliance comes not from electric lamps, but from its own intrinsic glow.

This powerful couplet is a warning against judging true inherent brilliance. Allama Iqbal tells us not to judge the natural glow (ताबनाकी) of a precious gem (जौहर) merely by comparing it to artificial lights, like electric bulbs. The gem's brilliance comes from within, not from an external source. It speaks to the concept of self-worth and authenticity, suggesting that true value is intrinsic and cannot be replicated by superficial comparisons.
