This sentence comes from Ji Bolun's prose poetry anthology "Sand and Foam". Perhaps the sea defines shells as pearls, and perhaps time defines coal as diamonds. This is a philosophical and poetic sentence, which expresses the witness and definition of time to the precipitation and transformation of things.
This sentence compares the sea to a shell, and pearls are precious gems formed by shells after a long gestation and tempering. Similarly, comparing time to coal, diamond is the crystal formed by coal under long-term geological action and high temperature and high pressure conditions.
This sentence means that every seemingly ordinary thing may become a precious thing after time's precipitation and transformation. It reminds us not to underestimate anything that looks ordinary or unremarkable, because they may become extremely precious and valuable after the baptism of time.
This sentence also emphasizes the precipitation and transformation of time, and the irreversibility and preciousness of time. Time can not only make a thing from ordinary to precious, but also make a thing from existence to extinction. Therefore, we should cherish time and make good use of it to make our life more precious and valuable in the precipitation and transformation of time.
The connotation expressed by "time defines coal as diamond"
Time is like a huge melting pot, which can turn ordinary things into precious things. This change is not achieved overnight, and it takes a long time and countless times of tempering.
In Ji Bolun's poems, the precipitation and transformation of time are not only reflected in the material level, but also in the spiritual level of people. He believes that time can precipitate and purify a person's soul and make his thoughts deeper and wiser. Just as coal is transformed into diamonds under the conditions of high temperature and high pressure, the human soul needs to undergo numerous tempering and baptism before it becomes brighter and brighter.
In a word, this sentence not only emphasizes the precipitation and transformation of time, but also emphasizes the irreversibility and preciousness of time. It reminds us to cherish time and make good use of every moment to make our life more precious and valuable in the precipitation and transformation of time. At the same time, it also inspires us to keep pursuing growth and progress, and makes our souls brighter and brighter in the baptism of time.
