I know somebody who is looking for resources on the
Sigalovada sutta (DN 31), and I knew that this group
would be a good place to start.
She is looking to get her hands on as many as possible
of all the known commentaries and translations written
in English, either on the Web, or in print somewhere.
There is Narada Thera'a translation on ATI, of course,
and I have a copy of our own Piya Tan's translation
that was sent to the list some time ago, which I have
passed on to her. But any other known resources would
be helpful.
