After reading several documents on Daoism, I find confusing how people use the three treasures. Reading chapter 67 from DDJ shows the 3 treasures although there is 3 treasures from other sources as jing, qi, shen and also refers to Chinese traditional medicine. Let me know how you understand and apply the three treasures.
There is another sequence of Three Treasures, 道 Dao, 经 Scriptures and 师 Teachers.
I think it is fair to say that only the persons who consider these things as Treasures will show the unshakable Intent to obtain them one day.
Once owned, the same Intent will be shown to protect them.
As they are Three yet hold together as One we can consider the three Treasures as a "body".
The sequential application of these Three Treasures works like this.
Dao cannot be transmitted without the Scriptures, Scriptures cannot be understood without a Teacher.
I think the Three Treasures of Dao, Scriptures and Teachers and the noble Spirit they should be treated with can help to make some judgements about the levels of scholarship Laozi tells us about in the 41st of the DaoDeJing and also why Daoists like to use capital letters.
