I saw it with my own eyes. I experienced it throughout my humble life. Some people call it karma and I think karma is a fact. It’s only natural that the universe operates in this manner; good begets goodness and bad begets badness. It is just all that simple.
My mum used to preach the above to us when we were much younger. You don’t need any religion to teach you that, although my mum was an avid reader of Buddhism. We, as human beings are able to comprehend that, but of course, some people opine that religion is still the central part in reinforcing it, or is it?
Can human beings still be good and moral even without religion? This is still very much in debate in today’s world. Do read about Richard Dawkins for an alternative view. In my humble opinion, it is not intended to distort you or denounce you from your religion. We just need to open up our mind sometimes and question everything. For that, it takes great effort and that’s why knowledge-seeking is never an accomplished task. And that's why, there are short-cuts, in fact, there are plenty of them that guarantees life or after-life in wonderful eternity, and that’s why the majority chooses that.
The universe has always been about cause-and-effect. It’s just common sense. Hence, do be aware of what we said, what we do and what we think as it will have an effect on you and others, and it will be on this lifetime of ours, whether immediate or the near future. I am no perfect either.
