What does "a thousand rivers and moons" mean?

What is the earliest origin of the poem "Thousand Rivers and Thousand Rivers and Moon"?

Thousands of rivers, thousands of rivers and moons have water. Origin 2007-04-08 10:59 edition 1:

Jia Taipu Deng Lu, one of the Zen Buddhism Deng Lu, Volume 18, Southern Song Dynasty.

In Qian Shan in the same month.

Every family is spring.

Thousands of rivers have water and thousands of rivers have moons.

Cloudless Wan Li days in Wan Li

Later generations interpreted the last two sentences as: the moon is like Buddha's nature, and thousands of rivers are like living beings. Rivers are big and small, and there is water and there is a moon; No matter how high or low people are, there are always people who have Buddha nature. Buddha's nature is in people's hearts and everywhere; Like the moon shining on the river, everything is reflected. Any sentient beings, as long as they have the heart to learn Buddhism, will have Buddha nature. Any river, as long as there is water, will have a bright moon.

There are clouds in the sky, and the sky is above them. As long as the sky in Wan Li is cloudless in Wan Li, the sky in Wan Li is blue. Heaven can be regarded as Buddha's heart, and clouds are troubled by material desires. When troubles and material desires are exhausted, the nature of Buddha's heart naturally appears.

Version 2:

According to legend, King Ashoka of India sent an invitation to all the monks and Taoist priests in the world, and everyone has already been there, except for the open hearth honour person, which was postponed until sunset and dusk. Wang Nai asked, why did you come so late? Open hearth furnace replied: I went to the feast of the world. Ashoka wondered, how can one get a feast in the world? The honorable man said: you don't know this! Then I wrote:

In Qian Shan in the same month.

Every family is spring.

Thousands of rivers have water and thousands of rivers have moons.

Cloudless Wan Li days in Wan Li

Version 3:

In the Ming Dynasty, Shen wrote a poem under "Guanyin Statue": "Word of mouth, each has its own response, and every family supports the general. Thousands of rivers have thousands of rivers and moons, and Wan Li has no clouds and Wan Li days. "

The last two sentences of the poem mean that there are hundreds of rivers with moon shadows, and every river has a moon shadow. Although the moon shadows are different, they are all illuminated by the moon; There are clouds flying in the sky, but the clouds are gone. The sky was originally clear. In the poem, Buddhism is praised, and it is likened to the Buddha's shining light and the unity of all laws.

This Shen is actually Shen Zhou, the head of the Ming Dynasty, who has a considerable position in the painting and calligraphy circles.

In A Dream of Red Mansions, the eyebrows are in vain.

I am Cao Jianlu from Jinling. If you miss lovesickness, you can't stop worrying about it. Have a graceful demeanour, Xiaoxiang, welcome by thousands, don't be ashamed of being young. No need to stay, love is short, and pain is not long. Go back to your thousand rivers and comfort me in a quiet autumn.
