The MZMC primer series is composed of short overviews of topics of interest in Soto Zen Buddhism and in Buddhism more generally. The series is intended to give readers a comprehensive, but brief, introduction to a topic. Each primer includes pointers to issues of relevance in a topic and a list of suggested readings. As a rule, the primers are no longer than six pages in length. The primers are a comfortable and informative way to start an introduction to topics of interest in Buddhism. As more primers become available, they will be added to those in the series below.
