Continue Talking about Dao!!

For my friend Fabio asking an interesting question with his special view, I am really happy to give supplement to this Dao/Tao again.
Fabio said, the Dao sounds like our science, particularly Physics. I have to admit that I also consider that Laozi’s Dao is composed of a large part of contemporary science, like Physics, chemistry, Astronomy etc. The difference in my esteem lies on that, the definition of Dao is a much broader one not only including the science, we have already known today, but also the domain, where we have not categorized out and organized theoretically. For understanding the latter one, here is an example. How do you think about the Chinese Reading Palm 看手相and Reading Face看面相. Is that purely constitution? At least for me, it is not, there is a kind of science in it, but what is it exactly? As far as I know there is a discipline named zhouyi(易学) researching on it. I can not say that Zhouyi is sophisticated discipline already, in fact, I have a lot of doubts in it. Nevertheless, it is just an example, which indicates that there are a huge space within our universe, where we do not know, have not figured out, or even have not any idea yet. Generally, Dao, is too deep and unpredictable, only because of our universe is too deep and unpredictable.

here, 道，可道，非常道 literally means Dao, may describe, but, it is very difficult to describe by language. This is what Chinese say, 只可意会， 不可言传。Only could be understand and feel, but can not be spoken out by words. Why？ except the reason I mentioned above, but also because...
Dao is a kind of experience and perception. Experience is a kind of thing could not diliver, for instance, if you do not know what love is, you would not understand why someone does some stupid thing like that, because you have not this kind of feeling and experiences on it, or although you have this experience, but you did not think of it, so can not have the feeling you should have, you either could not understand it. Another example, if you never go abroad for living or study, but heard a lot on it from others, maybe some opinion you are disagree or agree, which is not the real feeling for you indeed, since you need an experience, and then you can give an real feeling, even that, you can not describe the whole feeling out, which is a kind of 只可意会，不可言传。

Moreover, Dao, it is understanded or felt in status of calmness.
it means we need a calm status and mind to think, to feel...

On this topic, Fabio, as I mentioned, nobody is wrong. It is really happy for me to discuss it with you, and share my opion. ;-)
