Zen. And I don't mean the "mindfulness" kiddie-pool stuff 99% of so-called "teachers" blab on about.
From Kaiten Nukariya's 1916 gem "The Religion of the Samurai":
6. Great Men and Nature.
All great men, whether they be poets or scientists or religious men
or philosophers, are not mere readers of books, but the perusers of
Nature. Men of erudition are often lexicons in flesh and blood, but
men of genius read between the lines in the pages of life. Kant, a
man of no great erudition, could accomplish in the theory of
knowledge what Copernicus did in astronomy. Newton found the
law of gravitation not in a written page, but in a falling apple.
Unlettered Jesus realized truth beyond the comprehension of many
learned doctors. Charles Darwin, whose theory changed the whole
current of the world's thought, was not a great reader of books, but
a careful observer of facts. Shakespeare, the greatest of poets, was
the greatest reader of Nature and life. He could hear the music
even of heavenly bodies, and said:
"There's not the smallest orb which thou beholdest, But in his
motion like an angel sings."
Chwang Tsz (So-shi), the greatest of Chinese philosophers, says:
"Thou knowest the music of men, but not the music of the earth.
Thou knowest the music of the earth, but not the music of the
heaven."[FN#132] Goethe, perceiving a profound meaning in
Nature, says: "Flowers are the beautiful hieroglyphics of Nature
with which she indicates how much she loves us."
