2. From the professional knowledge, the word "three thousand" should be the virtual reference of numerals. What is the empty meaning of numerals? Take "Three Thousand Ladies in the Harem" as an example, the "three thousand" here will definitely correct the just three thousand beauties! Of course not. The "three thousand" here is only used to describe many beautiful women and is a quantifier. It is the same as "Three Thousand" in "Three Thousand Yue Family Can Swallow Wu". It seems that "three thousand prosperity" may mean that there are many things to express "prosperity".
However, from the perspective of Buddhism, "three thousand" has another meaning. The word "thousand" in Buddhism should be taken from the word "thousand" in Buddhism, that is, the boundless and complicated world in Buddhism. It seems that this "three thousand" is used to describe the size of the scope. Therefore, from the Buddhist perspective, the "three thousand" in the main question may also refer to a large area of the "prosperous" world.
