We can only do what seems most true and meaningful in terms of the teaching and our best understanding. After all, beauty is in the eye of the beholder. If we have attempted to ascertain the depth and breadth of the teaching, I believe validity will take care of itself. The problem is the WAY in which it affects daily life. If we keep it in general terms the distinctiveness of a tradition is lost.
Some religious paths lead people to divide from others.
We see this in some cults. Other try to be inclusive and bring people together in spiritual and social harmony. We need to clarify the principles of Shin Buddhism that could affect daily life, personally and in society. For many people it is simply saying nembutsu in the faith that one will be reborn in the Pure Land. That is one way to read it.
