For a particular situation you think that 'this' is the cause but when you go a little deeper, you will find that the cause is not there but it is somewhere else. So the cause keeps jumping. And believing that is the real cause makes our ignorance more concrete.
So when the whole universe is so complex, every event is complex, mind is even more complex, to get over this they brought this principle of Karma. And there is a lot about Karma — there is good karma and bad karma. And the karma that you do, you take the responsibility onto yourself, instead of blaming it on an event, situations, or people.
