What are the meanings of the three flavors in "San Tan Yin Yue"?

What are the "three flavors"? The ancients had two opinions. One is a metaphor for how people used to feel about reading. "Reading classics tastes like rice, reading history tastes like vegetables, and reading a hundred flavors like acyl sugar." These three experiences are collectively called "three flavors". The second is that the "three flavors" come from Li Shu's "Handan Bibliography" in the Song Dynasty: "The taste of poetry and books is too strong, and the history is broken, which is the three flavors." This is to compare poetry, history and other books to delicacies and to beautiful spiritual food; There are a pair of hugs on the pillars on both sides of San Tan Yin Yue where Lu Xun studied, which read: "Music is silent and filial piety is the only thing, and soup is a poem". It can be seen that the "three flavors" in San Tan Yin Yue should be used in this way. The third is to borrow Buddhist language. Samadhi is a transliteration of Sanskrit Samadhi, which originally refers to the three realms of reading Buddhist scriptures and understanding the meaning of the scriptures: one is "determination", the other is "acceptance" and the third is "equal holding", which means to stop distracting thoughts before reciting, so as to make the mind stable and focused; The attitude of understanding Confucian classics must be correct, and there must be all kinds of respect and piety; In the process of learning, you should concentrate on it and keep a consistent spirit. With the integration of Buddhist thought and Chinese culture, "Samadhi" gradually extended to a summary of the essential spiritual meaning of things, and some expressions such as "Samadhi" and "Samadhi" appeared to describe the accuracy and profundity of knowledge.
