Okay. Back to this.
Of the Chuang Tzu, the text attributed to a person named Chuang Tzu, there are three sections to the Chuang Tzu; Inner Chapters (1-7), attributed directly to a person named Chuang Tzu; Outer Chapters (8-22), attributed to followers/students of Chuang Tzu; and Miscellaneous Chapters (23-33), attributed to various un-named individuals.
Many years ago I did a concordance of the work of the TTC and Chuang Tzu. Because of something you have already mentioned I ended up with 119 Chapters. The way I constructed it was to take a concept from the Tao Te Ching (not necessarily a complete chapter) and then followed that up with supporting sections from the Chuang Tzu.
The only area where Chuang Tzu had little or nothing to say to what was in the TTC was where Lao Tzu talked about government. Chuang Tzu didn't say many nice things about government, and from my perspective, considering Chuang Tzu to have been an Anarchist, I can understand him not saying anything.
It is my opinion that if one has read only the TTC and not the Chuang Tzu one misses much of the meaning in the TTC.
