The Karma symbol derives from the Karma definition
. It looks like a wheel that never ends. And basically this is what does karma mean a life energies which live forever.
Many people want to see a picture of Karma symbol but how many of them really know what is Karma definition? It is very similar to physics lesson, energy will never go lost it is just transform to something else. This is also the case with your actions: if you are a good person and help others that you will get good things back into your life. Whether it is help back, happiness or even success in your life. But if you are wasting your time on negative energies and complaining all the time about other people and how the world is unfair you will end up in the worst places on earth.
Instead of being angry all the time, try to focus on much positive point of view about this world. It is also very unhealthy to be sad and angry it can really brings diseases to your life like a heart attack. It is also much recommended to do some relaxations exercises. So after you decided that you like to live a healthier and happier life you are ready to the second stage which is creating a good karma. In this way you have to separate your thinking from the self and think about other people. It is so similar to imagine you future but you are doing it while you help others. So in the end not only your future will be nicer but others fate will be also better.
People often think that if they have bad karma someone else might cause it. But it is just not true. The Karma symbol and Karma definition are not curses or spells that some psychic or magician can cast. If you have bad energies it is because of you only. To blame someone else is to ignore the problem and this will not solve anything. Sometimes we feel trapped into life circumstances but at any giving time we have the free will to leave or adapt to this situations. It is all about how you choose to do it.
