In creating peace within ourselves, we create peace in our world. Like energy attracts like energy. If we are joyous then we attract people who are joyous and joyous things happen to us. If we are angry, we tend to attract angry people.
We all get a mixed bag. It's a tendency. No one is ever completely perfect--unless you are the Buddha, so bad things can still happen. However, when we focus on the bad things that happen rather than what we learned from the situation, we tend to create more negative energy, making it harder for things to turn around for us.
The more we recognize that the energy that is inside us is attracting people and events into our lives, the more we can work on changing ourselves so that we give off the energy to attract those things that we hope to gain. If we begin from a stance of selfish gain by doing this, no doubt we will attract to us many situations that show how selfish and self serving most people are. If we do this from the standpoint of making the world a better place, we have a much better chance of making real change and drawing good things to ourselves.
It sounds easy, doesn't it? We feel like failures if it doesn't work. However, no one has completely pure energy, as I said before. We all have a subconscious full of things we don't want to look at. The more we work on ourselves and creating peace within ourselves, the more likely it will be that when a disaster happens to us, we may be able to find the good inside it. If we are trapped in traffic and late for our appointments, perhaps the people around us may all be very interesting and helpful and willing to share water. If we are rear ended, perhaps the driver is insured rather than uninsured. Small things and the way we greet them make a difference.
With the laws of attraction, the energy we put out is the energy we get back. The Universe doesn't listen to putting on a happy face while seething inside. It knows. If you are angry, it's better to show it and let it go. Then you can get to the joy. If you are seething quietly and insisting that everything is all right and that you are looking on the bright side, the anger festers, and it's sure to attract more angry energy back.
We can't always be happy and joyous. When we feel otherwise, it is important to let it out. Let that go. Then get back to what's really important and we may find that we are feeling more peaceful. Then so will the world around us.
