Shunryu Suzuki was ordained as a novice monk in Japan as a boy, entering training years before any American student had heard his name, a documented early monastic formation distinct from the temple-priest-turned-teacher story his first article tells beginning in 1959. He trained under Gyokujun So-on, a strict Soto Zen master unrelated to him by blood, at the temple Zoun-in, a documented teacher-student lineage distinct from any account of Suzuki as a self-taught or informally formed priest.
He went on to serve as a Soto Zen priest at temples in Japan, eventually becoming abbot of Rinso-in, before he was asked to take up a posting at Sokoji temple in San Francisco to serve its Japanese immigrant congregation, a documented ordinary clerical career distinct from any indication, prior to that posting, that he was bound for the wider American audience his first article describes finding him almost by accident. His decades of formal training under So-on at Zoun-in gave him the grounding in zazen practice and Soto ritual that he later taught, informally and without system, to the Americans who began attending his class.
That the priest remembered for teaching zazen informally to a largely non-Japanese student body in San Francisco had, decades earlier, gone through the same strict formal training under Gyokujun So-on that any Japanese Soto priest of his generation received, marks Suzuki's own American teaching as a documented case where an unsystematic, welcoming style rested on a formation that was, in Japan, anything but informal.
