‘Ancient masters [Yangshan and Guishan] said to each other, “What is the wondrous clear mind?” “I say it is mountains, rivers, and the earth; it is the sun, the moon, and stars.”
Thus we know that the mind is mountains, rivers and the earth, the mind is the sun, the moon, and stars. What is said here is not more, not less.
Mountains, rivers and earth mind are just mountains, rivers and the earth. There are no extra waves or sprays [in this mind]. The sun, the moon, and stars mind is just the sun, the moon, and stars. There is no extra fog or mist. The coming and going of birth and death is just the coming and going of birth and death. There is no extra delusion or enlightenment. The walls, tiles and pebbles mind is just the walls, tiles and pebbles. There is no extra mud or water. Four great elements and five skandhas mind are just four great elements and five skhandas. There is no extra horse or monkey. The chair and whisk mind is just the chair and whisk. There is no extra bamboo or wood.’ (Shobogenzo Sokushin Zebutsu)
We always want to add something (I am guilty of it just by writing this), to add in our two cents’ worth, have our opinion heard. It is not necessary.
