The Spinning Leaf is a Mental State, the opposite of the Heart of Stone. It's a mental state where the user simply "goes with the flow," letting his mind free to wander wherever it wants, talking and doing things without thinking twice about it, just doing it, no thinking. Kvothe is the only person explicitly described to make use of this mental state in The Name of the Wind or The Wise Man's Fear , but Vashet mentions that a similar type of meditation is practiced in other Ademre schools of the Lethani. Indeed, Kvothe uses it to have a better grasp at the Lethani.
