Khudi is the beating heart of everything Iqbal wrote. The word is usually translated as 'self', 'ego', or 'selfhood' — but each translation slightly misleads, because in ordinary speech those words carry a whiff of vanity. Iqbal's Khudi is the opposite of vanity. It is the plain fact of your own individual existence — the 'I am' at the centre of you — together with the lifelong project of making that 'I am' real, strong, and worthy.
To see how radical this was, you have to see what Iqbal argued against. Centuries of mystical poetry before him had treated the self as a problem to be dissolved — the dewdrop slipping into the ocean, the ego extinguished into the divine. Iqbal admired that tradition and then broke with it. The dewdrop, he insisted, should not lose itself in the sea; it should learn to contain the sea. The goal is not the annihilation of the self but its intensification.
How is Khudi strengthened? Through desire, through love, through action, and through facing resistance rather than fleeing it. A self grows by wanting greatly, by committing, by meeting hardship squarely. It weakens through dependence, imitation, fatalism, and the comfortable surrender of one's own judgement to the crowd. Khudi is not handed to you; it is built — or left unbuilt.
And the reward Iqbal promises is the most audacious line in Urdu poetry: raise the self high enough, and destiny itself will pause to ask you what you want. The fully realised self is not fate's subject but its consultant.

Khuda bande se khud pooche, bata teri raza kya hai
Tu agar mera nahin banta na ban, apna to ban
Ye bhi mumkin hai ki tu maut se bhi mar na sake
