You are the centre of that world. That is the world you live in. Now how will you change the world? By changing yourself.
You and the world should stop thinking of changing each other. Just allow a third person to do the needful. You know who I mean: God, the only Doer.
Be content with what you have; rejoice in the way things are. When you realise there is nothing lacking, the whole world belongs to you.
The world will be balanced when we are balanced.
Yesterday I was clever, so I wanted to change the world. Today I am wise, so I am changing myself.
