Teachers at Two Arrows Zen Center

Two Arrows Zen teachers, Diane Musho Hamilton Sensei and Michael Mugaku Zimmerman Sensei are members of the White Plum Asanga, and the Soto Zen Buddhist Teachers Association. They have adopted the White Plum Asanga Code of Ethical Conduct. 

We who have been recognized as teachers in the White Plum lineage respect the responsibilities of leadership and of being teachers within our sanghas. We acknowledge our role necessarily gives rise to a power differential in our relationships with students and other sangha members, and for that reason alone, our words and actions can carry great weight. With awareness of this fact, we agree to strive to adhere to this Code of Ethical Conduct as teachers within the White Plum Asanga, a code based on principles of trust, integrity, justice, respect and accountability, in order to nurture an atmosphere supportive of the practice of the Dharma.  
We also agree as teachers that we will take steps to assure that individual sanghas promulgate codes of ethical conduct and grievance procedures that are grounded in the principles set forth in this Code of Ethical Conduct and WPA Grievance and Reconciliation Procedures. Those individual codes should govern the conduct of the teachers and sangha members subject to them.  We affirm that as teachers, both we and the individuals who constitute our individual sanghas have primary responsibility to assure that sound ethical principles inform all aspects of practice life.  In the event that an individual sangha does not have such a code, this Code shall be the applicable standard governing the teacher and members of that sangha.

Michael Mugaku Zimmerman, Sensei

 "This day will not come again. Each moment is a precious gem."

     Mugaku Sensei came to Zen relatively late. He first ventured into meditation in 1993 as a way to find some grounding during his first wife's year-long struggle with terminal cancer. Shortly thereafter, he met Diane Hamilton, now Musho Sensei, through their working together for the Utah courts. At her suggestion, he attended an introductory class at Kanzeon in early 1997. Soon after, he began to study with Genpo Merzel Roshi. He and Diane were married by Genpo Merzel Roshi in 1998, the year he received Jukai. They received Shukke Tokudo and became monks together in 2003, were joint Shushos during the Spring Ango in 2005, received Denkai in early 2006, and he received Dharma Transmission in December 2006, seven months after Diane. Together they have four children. Michael is an active appellate lawyer in Salt Lake City.
