Gold or Iron

Gold or Iron, What do thee want, Most of us would say gold, Because that's what is used to flaunt. But what if I vanish iron from the world, Lavish houses will collapse, Luxury buildings will perish, Recovering from it will take a huge lapse. Now imagine if gold gets extinct, Nothing will perish, Nothing will be demolished, But still it's gold that people cherish. That's the sad reality, Of this world's thinking, People only see outer appearance, And consider it the king. The true work is done by iron, Unfortunately, it gets no recognition, But it has the inner beauty, What I call perfection.
