What is the poem "Reading Comprehension" used to describe that "learning new knowledge can lead to a new realm"?

How can the canal be so clear? Because there is running water at the source.

The specific original text is as follows:

Reflections on Reading (I)

As soon as the half-acre square pond is opened,

The sky is full of clouds and shadows.

It is the source of living water.

theme

This poem is inspiring and timeless. Half an acre of pond is like a mirror, reflecting the sky and the clouds flashing back and forth. Why is this pond so clear? It turns out that the source of living water is endless! Poetry has profound meaning. Learning is compared to the source of living water. Only by constantly absorbing new knowledge can we make rapid progress.

Some people think that poetry is the product of thinking in images, so it is only suitable for writing scenery and expressing feelings, but not for reasoning. There is some truth in this statement, but it cannot be absolute. Because reason can be expressed by visual means, it is as attractive as scenery and emotion. At the same time, the speculative nature of reason itself is often very fascinating. (Meicheng's "Seven Hairs" just proves this point. Therefore, there are many successful philosophical poems in ancient and modern poetry. Zhu is a student of Liu Zikai, and he is also very close to his father Zhu. Perhaps influenced by his father and teachers, his evaluation of literature in Taoism is relatively fair, and he has also written some good poems full of life flavor. For example, these two songs are, of course, works of reasoning. The first is that the pond needs continuous injection of living water to be clear, and metaphorical thinking needs continuous development and improvement to be active and avoid stagnation and rigidity. The completion of the latter song often has a stage from quantitative change to qualitative change. Once let nature take its course, the appearance is clear, free from sentences and binding. These two poems express the truth they have learned in their study with vivid images, which are both enlightening and poetic, so Chen Yan rated them as "reasoning with things without corruption".
