If there is a raging current of blood in your veins, what gain is there other than the burning agony of the heart's life?

This profound couplet challenges the very definition of life. Allama Iqbal suggests that simply having physical life—the mere flow of blood in our veins—is insufficient. The true essence, the real 'gain' in existence, is found in the intense, passionate burning of the soul (saz-e-jigar). It speaks to a life lived with deep emotion, passion, and spiritual fervor, rather than just biological survival.
