Thinking about Su Shi's comparison between water and the moon in "Red Cliff Fu", what does it mean? Besides, what else does Su Shi's words contain?

water and moon. Su Dongpo, a great writer, seems to have a special liking for "water" and "moon". Whether it is the opening scenery, the lyrical reasoning in the novella, or the fun between the host and the guest, it is always done by grasping the key images of "water" and "moon". "Water" and "Moon" are a red line that runs through the whole text, connecting the feelings, scenery and reason in the text in series, which makes people feel that they are always in the mutual reflection of moonlight and underwater sound. At the beginning of the article "Water" and "Moon", "Perilla and her guests are boating under the Red Cliff", which means "I hope in July". Just when the moon is full, it's still early, and the moon is not out of the mountain. Looking at the river, it's "water waves are not exciting" and the water is quiet, so I am happy to drink with my guests and wait for the moon, and "recite the poem of the bright moon and sing a song" At this time, the author's mind is as calm as water, his wine is high and his poetry is full of emotion. It is a good time to enjoy the moon, so he naturally chants "the poem of the bright moon", and his eyes lead to the moon in the poem. But why can't he understand that Su Zi intends to lead to the real moon with the moon in the poem? A moment later, "the moon rises above the Dongshan Mountain and lingers between bullfights", the bright moon is in the sky, the water surface is like a mirror, and the world under the moon is "white dew across the river, and the water meets the sky". This is Su Shi's poem in "Fu on the Former Red Cliff", which focuses on describing the two beautiful images of water and moon in the face of the beautiful scenery of Chibi and the singing of boat boats by the host and guest. Water is the water of the Yangtze River in July and the Mid-Autumn Festival in August. At that time, the water was "the breeze in Xu Lai, the water waves were stagnant" and "the white dew crosses the river, and the water meets the sky"; At that time, the moon "rose above the East Mountain and lingered between bullfights". The water is boundless and graceful, and the moonlight is rich and pleasant, and it shines with the water phase. If the water is boundless, the moon is boundless. I don't know where the water is and where the moon is, but I feel that I am in an "empty and clear". Thousands of pores are stretched; All worldly concerns are thrown away together. So it led to "the vastness is like feng Xu's wind, but I don't know where it ends;" The feeling of extreme freedom is like being independent, feathering and becoming immortal. This is the reappearance of the long-lost spiritual freedom in prose since Zhuangzi. Feng's "emptiness" means that he swims in the "emptiness and brightness", which integrates the color of water and moon, and can get the essence of the intersection of water and moon better than Xie Zhuang's "Yuefu" and Zhang Ruoxu's "Moonlit Night on a Spring River". Because Xie Zhuang borrowed the moon to write about lovesickness, the moon is in the sky; Zhang Ruoxu's feeling of life is aroused by the hidden moon, and the moon is outside his heart. Su Shi, on the other hand, felt the beauty of the water moon with his heart-only in this way can he find the word "empty and bright" to describe the harmony between the water and the moon, and the incomparable iron paste and freedom it gives people. And the feeling of "vastness" and "fluttering" is naturally produced by the guidance of the beauty of Shui Yue. "Feng Xu defends against the wind" and "Feathering and Ascending to the Immortal" are all things recorded in Taoist classics to show that they are extremely free and do not care about the world. They mean that not seeing the water and the moon, but only feeling empty and bright is not only the inducement for the author to get rid of vulgar feelings, but also the external metaphor of his spirit after reaching empty and bright. From this, you can see the emptiness. The empty and bright realm is an inorganic realm where all worries rest, while Shui Yue is a meaningful image that can filter people's worries and make them think freely. On weekdays, the interest falls on the view of Confucius, and he regrets time and existence. Li Baizhi, who has a natural and unrestrained personality, calms down his homesickness because of the bright moon, which can best show this spiritual orientation of Shui Yue. Zen Buddhism believes that it is a metaphor of thought. "Thousands of rivers can be reflected in January, and thousands of rivers can be taken in January." Based on the relationship between January and the moon of a thousand rivers, Yan Yu's dialectical relationship between self-nature (Buddha's nature) and otherness (all-nature), being and not being, changing and being constant, pays more attention to the indiscriminate consciousness among the differences in the world. Therefore, the image of the water moon is also the entry point for Buddhists to participate in Zen Buddhism. Zen thought was deeply rooted in the hearts of the people in Song Dynasty, and Zen thought was aided by Neo-Confucianism and Zen metaphor was aided by poetics. Most scholars regarded Zen thought as a compatibilizer of thought, and Su Shi was no exception. On this empty and quiet night, Su Zi had a secret love affair when he saw the water moon. In this quiet night, he transcended the ideological limitations of gaining and losing others, entered Zen from Taoism, combined Taoism with Zen, looked up at the universe, looked down at himself, reflected on the nature of himself and the universe, and entered the realm of philosophical ontology thinking. Like Shi Zi, he also uses Shui Yue as a metaphor. In the Shui Yue, which seems to never disappear-"The dead are like this, but they have never gone", "Those who are full of deficiency are like that, and those who die don't grow or decline"-he feels that eternity is also lurking in his body: "If you look at it from the unchanging, things and I will be endless." In this way, even knowing that everything has changed in a small period of time, "heaven and earth can't be in a flash", I am happy because I have the nature of "changing while keeping the same" consistent with the universe of heaven and earth, and I am satisfied with my integration into nature and acquisition of naturalness. The Zen thought gained by thinking through the realm of freedom is like Buddha's light, which makes him release the depression and depression accumulated for a long time in an instant, and his spirit and body relax together in this empty Zen realm. Bathed in the endless breeze and bright moon, the host and the guest got rid of it together, became free, and slept peacefully in the water moon wonderland, as if they didn't even bother their dreams.
