网友的句子不完整。mystical 是形容词，后面缺少一个名词。
So it was possible for third-century Confucianism to gloss over the most obvious differences by asserting that the way, inherent in all things, is to be experienced in its totality through mystical + 名词.
1. 基本结构：it was possible for sb. to do sth.
2. by asserting that ...为不定式的方式状语。 that ... 是 asserting 的宾语从句。宾语从句的结构是： the way is to be experienced。
3. inherent in all things 作 the way 的定语。
