Or another way to say it is do not go with things that are unnatural. Here is my interpretation at the present moment of what Taoism is about in one aspect.
Have you ever found yourself in a real psychological difficulty? I’m talking about depression, anger, obsession, all the bad things. It is not natural to be psychologically disturbed. My theory states that if you are obviously having a non-natural difficulty it is because the upsetting situation you got into came about not-naturally. Therefore, only do what is natural.
If you’ve forced a situation to occur generally the results are not positive. They are hard to deal with and that is not natural. This happens because you forced the situation rather than letting a different situation naturally occur. If you find yourself having to deal with some really tough thoughts or patterns of thought then maybe try saying to yourself that this is not natural. You are having a not natural reaction to a situation that did not occur naturally. Both the situation and your reaction were not natural. Therefore, you have to let it go. It was not real. It was forced or contrived and simply not rooted in the only thing that has any power – nature or naturally occurring things.
Nothing in nature is trying to be something it isn’t. That is why nature works so well and is so astounding. Go with your own nature. Don’t try to be something you aren’t, don’t try to have something that doesn’t come on it’s own, don’t force anything.
I hope this sheds some light onto the formerly confusing (for me) phrase “go with the flow” or “go with your own nature.” In the future to avoid unnatural reactions (which are miserable and hard to break) you should only do what is natural. You have no power to create things that are not natural.
