This is the poem by Bai Juyi describing meditation on a moonlit night.
Era: Tang Dynasty
Author: Bai Juyi
Work: Autumn Thoughts
When I am sick, I have few dreams at night, but I have many thoughts at the beginning of autumn.
Loneliness comes after rain and clear weather, depression comes early and cold comes.
Birds perch on the red-leafed trees, and the moon shines on the moss ground.
What’s more, I am middle-aged and over thirty-two.
