Together with some friends, we have setup a sutta study group where we will gather monthly to read and share our understanding on Suttas.
So far our approach on selecting of Sutta for the group discussion seems to be rather random and based on what we can think of at that point in time.
I wonder if you are able to recommend a list of Suttas starting with those that focuses on the lay life and we can apply the principles more easily, progressing to other deeper and more abstract concepts for the Sutta study group discussion?
Under this topic a number of suggestions for readings were given, which would very likely fit the purpose of your study group. Other than that, I agree with @LXNDR that Bhikkhu Bodhi’s “In the Buddha’s Words” is one of the best and could be studied in your group in the way he describes. I also found this book immensely helpful myself.
