We often wish to change things around us, we often wish to change the world. But the world is a mere reflection of the sum total of all of us. So, the change outside needs to start within you.
Often, things disturb us and we resolve to change them for the better. It's idealistic. But idealism is much needed. Idealism creates new ideas, breaks social taboos, and structures, and destroys community evil. It happens when you resolve to change. A change which starts from within.
Being restless about the outside world will create internal restlessness within. The outside world does not belong to you. Be calm at outside turbulence. You will be judged for your inner self. Pay attention to that. Change starts from within.
