Dear Members,
Namaste.
Prof. Dragomir Dimitrov's "The Legacy of the Jewel Mind" (2016), page 10, fn 27 says:
"English translation of Zhao's catalogue entry: There are more than six chapters available. ... Folios 272-297 belong to the 7th chapter, but are incomplete."
The published materials so far are available only up to ch.6. Chapter 7 must belong to the Vedic morphology, because as per चान्द्रवृत्ति, ch.8 must be dealing with the accent rules - "स्वरं तु अष्टमे वक्ष्यामः।"
