Destiny, you know what I wanna be
To me this showed a very subtle aspect of the character Hamza, the concept of a karma yogi. His focus towards his goal, his tapasya to achieve that goal and going beyond the realms of humanly limitations to achieve the state of a yogi, the highest form of human capabilities.
A yogi meditates for years just like Hamza and achieves thus highest form to realise enlightenment or God.
That's why after the Major Iqbal final battle scene, when Hamza shoots the chain at Major Iqbal, it was not another humanly attack of his, but the "Wrath of God".
This tapasya helped jaskirat to transform to Hamza with a lazer sharp goal to work for his country.
Personally a lot of things were going on in my life and these scene just made me realise that among all the confusion and chaos, we all have a destiny, a goal, for which we breathe for till we reach the best version of ourselves. We are all capable of it.
(And that's why I love Dhurandhar❤️)
