The usual translation of the Japanese word nin is “patience”, but “constancy” is a better word. You must force yourself to be patient, but in constancy there is no particular effort involved – there’s only the unchanging ability to accept things as they are. For people who have no idea of emptiness, this ability may appear to be patience, but patience can actually be nonacceptance. People who know, even if only intuitively, the state of emptiness always have open the possibility of accepting things as they are. They can appreciate everything. In everything they do, even though it may be very difficult, they will always be able to dissolve their problems by constancy.
