Zen perception of the now is anchored in spontaneity, simplicity and total awareness.
You understand a joke spontaneously. Your perception of the humor usually is not analyzed or studied before you simple smile or laugh. No amount of explanation or intellectual analysis can explain to a person who does not have a sense of humor why the joke is funny. You get the joke or it escapes you, even if you fake the laugh you still haven’t got the joke.
In the same way you must experience the awaking of Zen Buddhism directly. You either get it or you do not. Satori cannot be learned, it must be experienced through your personal newly found awareness.
All things change when we do.
