Iqbal’s concept was the most significant metaphor that embodies strength and freedom as well as the relentless pursuit of lofty ideals.
To him “Shaheen” is not just a bird, rather it symbolizes youth who possess exceptional qualities and characteristics. It is symbol of strength, vision and freedom. An Eagle soars high above untethered by earthly limitations echoing Iqbal’s vision of the perfect man. 
In his first poetry book, “Bang-e-Dra”, the concept of “Shaheen” appears in various couplets. He uses the image of eagle to inspire young ones to be free from shackles. He urges them to embrace inner strength and pursue life of a purpose. Shaheen in Iqbal’s view is seeker of knowledge and wisdom. His youth is not bound in limits or forced circumstances but possesses courage and determination to even transcend boundaries. It strives for self-realization as well as self-improvement.
To him, Shaheen is symbol of freedom. Iqbal envisions a society where young ones liberate themselves, like eagle, from chains of ignorance and fear. He encourages his readers to strive for intellectual freedom and independence of thought. His ‘Shaheen’ believe in own abilities. So, let's take inspiration from his words and work hard to become brave, curious and determined individuals who can make a positive impact on the world.
Tu Shaheen he parwaz he kaam tera 
Tere samne aasman aur bhi hein
