This Liu Zhi is evidently an ancient sage of the Wuliang Mountain, and he dissected every sentence of the "Wuliang Heart Sutra," sharing his own insights and reflections on each.
It can be seen that Liu Zhi's cultivation is extremely high, exactly how high Ling Zhenfei is not clear, but his understanding of cultivation is exceptionally thorough.
Although the Wuliang Heart Sutra doesn't have much use for Ling Zhenfei, reading this elder's experiences greatly expands one's knowledge.
Liu Zhi seems to be a man of deep feelings, but he likes to obsess over details; otherwise, he wouldn't have researched the "Wuliang Heart Sutra" for thirty years.
Among Liu Zhi's writings are some interesting things, such as how Liu Zhi initially treated the Wuliang Heart Sutra as a Dharma Gate for mind cultivation—because why else would it be called a Heart Sutra?
Yet after several years of cultivation, he discovered the Heart Sutra turned out to be a method for body cultivation.
