The concept of Buddhist teaching was invented about 2500 years ago. Buddhism can help you remove the evil inside you that is making your life hard by giving stress. The Buddha traveled around the world and knew how to get rid of stress by meditation so whatever he told was true. If you pay attention then you will see that the people who follow Buddhism do not enter in conflict and will be calm always you will see that they are really solved with their life than the normal people. If you study Buddhism you will eventually gain more and more interest in it.
The main aim of Lord Buddha who invented the Buddhism religion was to balance the life to get salvation. If you start to follow the teaching of Buddha you will see that your life is getting solved and you will see everything with positivity. You will have joy in your life and will be very peaceful. The Lord Buddha spends his whole life in searching for the truth. Buddhism helps us to reach the truth of life but needs a lot of concentration and dedication to reach a high level like this.
According to Buddha, there are three marks of existence, the first one is Anicca also known as impermanence this means that life is not constant. If we reach a high level of meditation than we will come to know that it is true. The second one is Anatta it means not self according to Buddha we do not exist on our own. And last but not the least is Dukkha which is also known as dissatisfaction. Buddha said that if we do a high amount of meditation than at one point in time we will get satisfied by what we have in our life.
