Chovot Halevavot, the classical work on Jewish ethics, was authored by Rabbi Bachya ben Yosef ibn Paquda (the first "Rabbeinu Bechayei") on or before 1161, and translated into Hebrew from the original Arabic by the famed translator R. Judah ibn Tibbon in 1167. It was first published on the 25th of Tevet of the year 5319 from creation (1559).
The Rebbe describes the following as a core teaching of the Baal Shem Tov:
Not only are the pirouettes of a leaf as it falls off a tree,
the quivering of a blade of grass in the wind,
and all the details of the world around you
all brought into being, given life and directed every moment from Above—
but beyond that:
Every nuance is an essential component of a grand and G‑dly scheme, the gestalt of all those vital minutiae.
Every moment burns with the pulse of G‑d’s desire.
Meditate on this. And then think:
How much more so the details of my daily life.
