When I go on meditation retreat, I often hear some version of these words: "You don't speak forthree whole days? I couldn't do that." It's interesting that not talking is the deal breaker. There are many hard parts of a meditation retreat: judging mind, fear, doubt, and physical discomfort. On retreat, there's no place to hide. I get an honest look at myself and that's difficult territory. But not speaking, that's a gift.
