Book of Changes (1,5)
I believe the answer is:
i ching
'book of changes' is the definition.
(ancient Chinese text)
This is the entire clue.
(Other definitions for i ching that I've seen before include "Bk. of Changes (Chin.)" , "Chinese book of wisdom" , "text from China" , "Ancient Chinese manual of divination (the Book of Changes)" , "Ancient text" .)
