Seems like the first teaching in Crystal Cave is removed,"The Treasure of the Lotus C'rystal Cave, the direct instructions of Sri Singha", everything else seems to be there including at least one pretty fantastic teachings of Sechen Gyaltsab, Dilgo Khyentses root Guru, that wasn't in the original book.
"The direct, hard to understand, subtle field of knowing, the Great Path, is non-conceptual (akalpana), and entirely beyond the grasp of intellectual thought. Divorced from verbal ideation, it is difficult to point out and as difficult to enquire into. It cannot be communicated through words and [therefore] is not within the scope of the neophyte (adikarmika). Nevertheless the path is to be approached through studying scriptures (sutra) of the World-Teacher and following the personal instructions (upadesa) of one's Guru-ji."
