Just like there is the law of gravity, there are laws of nature which are called the laws of karma. Laws of karma are not subjected to interpretation. They act whether you believe in it or not.
If I tell you, there is no law of gravity, and what goes up in the air does not have to come down, then will it really matter to anyone? Even if I write a hundred thousand volumes of books in eloquent philosophical language to prove and to convince you, that the law of gravity is simply created by a sentimental fanatic who could not cope up with the realities of life. By saying so, would the law of gravity cease to function? The fact is – it would continue to function as it always does.
Similarly, there are the laws of nature. The law of thermodynamics says for every action there is an equal corresponding reaction. That is scientific; or just like lord Jesus said very beautifully in bible, ‘As you sow, so shall you reap’. The mills of God grind exceedingly fine. But sometimes very slow as well. Whatever you do whatever you speak there is going to be a reaction. That is the law of nature.
Now in the laws of state, you can get away with certain things. You can kill a hundred people but the law of the state is going to kill you only once. But if you kill a hundred people, the laws of nature can kill you a hundred times or a thousand times or a million times. So the laws of nature cannot be escaped, you cannot get around it, you cannot bribe Yamaraj (the God of justice). You cannot buy justice in the law of nature. Everyone is equal. These are the laws of karma.
