Meaning is an interesting word and possibly now so more than ever. Meaning is something we tend to take for granted, as in you know what I mean. Actually used this way it is more a barrier to understanding somewhat like the phrase: "everybody knows that!" I suggest that Zen is meaning in a more usable sense:
"Even though waves arise, the essence of your mind is pure; it is just like clear water with a few waves. Actually water always has waves. Waves are the practice of the water.. To speak of waves apart from water or water apart from waves is a delusion. Water and waves are one." - from Zen Mind, Beginner's Mind by Shunryu Suzuki-roshi.
Taiun Elliston-roshi , Abbot of our Silent Thunder Order, puts it this way:
At first, our Zen practice is like a comma in a sentence. We interrupt the normal flow of our daily activities from time to time and pause to meditate. Briefly, like a comma, or for a longer time, like a semicolon; or coming to a full stop, like a period. Afterward, we resume the sentence of our lives. And of course, we encounter a lot of question marks??? And the occasional explanation point! These latter are what keep us going: those eureka! or aha!
