Hello, Odion et al -
We left SGI-USA for a variety of reasons. "We" in this instance indicates a group of about 10 families. Some of the reasons were doctrinal, but most at the time had to do with disagreements with SGI-USA's positions regarding what constituted ethical behavior, both as an organization within the business community, between the organization and its members, and within the organization between members and leadership. A lot of this revolved around our feeling that standard rhetoric and actual behavior differed greatly. Some of this was international or national, but a lot of it was local to Houston SGI-USA. A good part of our discontent was related to the behavior of SGI & SGI-USA regarding the split with Nichiren Shoshu, but that wasn't all of it by any means.
Roughly 18 months after drifting away from SGI-USA, we were introduced to Nichiren Shu. We were much more comfortable with the doctrinal stances of Nichiren Shu, as well as being more comfortable with the business model (akin to "standard" Protestant Christianity in the US) and the internal dynamics of Nichiren Shu sanghas. Most of us decided to take refuge with Nichiren Shu (taking refuge is a formal way of saying to join, BTW), and to create a Nichiren Shu sangha in Houston. Several families later split off because they were not interested in expanding the sangha into a Temple, and the rest of us were. A couple of families have returned to SGI-USA, some more participate in a UU-Buddhist group, and the rest make up the founding membership of Myoken Temple.
Is this what you were interested in?
