It's a topic to introduce "Taoism" which is ancient Chinese thought.
As for the best King, everybody knows the King.
The second best King is praised by everybody and is liked. The third best King is afraid of by everybody. The the worst King is made a fool of by everybody.I write teaching of Taoism in this way
Not sure what I should understand from that.
"When wise students hear about the Dao, they follow it with care. When ordinary students hear about the Dao, they sometimes believe in it, and sometimes doubt. ...
I have laughed out loud many times when reading the Dao De Jing
Hm, first 3 minutes or so was all about indian stuff (sanskrit, karma and so on), then some zen, and a lot of personal interpretation which I do not necessarily adher to. Then I stopped watching
Taoism is a distinctly Chinese thing. There is the concept of de, which both has to do with virtue and "good karma", but I would stick to that word instead of "karma" when talking about taoism
Zen as I understand it is a kind of blend of taoism and buddhism and maybe something more. It is not "pure" taoism. The personal interpretations may hinder further progress if one want to go far.
Because of this I would recommend reading the dao de jing (tao te ching) and other taoist classics if one really wants to understand taoism. Maybe also the taoist directed "wings" of the yi jing
If you want an easier to understand intro for westerners, I suppose such videos help a bit, but I would suggest "the tao of pooh" and "the te of piglet" (there is also a book that combines the two)
All that being said, don't believe me blindly. "He who talks does not know, he who knows does not talk" - Dao De Jing. I suppose you should follow your own way, whatever it might be.
One more thing. The Dao De Jing is only about 5000 words, I suppose you can read it all in an hour or so. It is also cut into small standalone parts. But it's deep, understanding can take a lifetime
