The strength of faith of the Lay Priest of Ko

The human mind is inconstant; it is ever-changing and unfixed. I thought it wondrous that you pledged faith in my teachings while I was in the province of Sado, and your sincerity in sending your husband all the way here is even more remarkable. The provinces we live in are far apart, and months and years have passed, so I was concerned that you might slacken in your resolve. However, you are increasingly demonstrating the depth of your faith and accumulating good deeds. Surely this is not a result of practice over just one or two previous lifetimes. 19/4
