Although there is only one moon in the sky, as long as the river is quiet, thousands of moons can be reflected; When the clouds cleared, the bright sky naturally revealed the radiant sun.
Philosophy:
In the previous sentence, the moon is like Buddha's nature, and thousands of rivers are like sentient beings. No matter how big or small the river is, where there is water, there is the 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.
The last sentence, 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.
This poem comes from Volume 18 of Jiatai Pudeng in Song Dynasty. It is a very high-level Buddhist proverb.
Extended data
"Rivers are thousands of miles away, and rivers are thousands of miles away." There is only one moon, but it reflects different reflections because of different waters. Today's month is by no means an ancient month, and tomorrow's month is hardly today's month. The world in everyone's eyes is different, so the bright moon in everyone's heart is different.
"Rivers are thousands of miles away, Wan Li is cloudless, and Wan Li is cloudless. Thousands of rivers represent different people, the moon represents Buddha's nature, clouds represent troubles, and the sky represents a pure and unpolluted heart. Because there are dark clouds in the sky, we can't see the clear sky; The human mind is polluted, so we can't really understand the truth of life in the universe. As long as you get rid of the haze in your heart, your heart will be purified and your heart will be bright again.
