Soto Zen: A Tale of Two Founders?

A while back, I talked about the history of Zen [particularly Rinzai Zen] and the samurai class in pre-modern Japan. Rinzai has a particularly convoluted history compared to other Buddhist sects in Japan due to its multiple waves of immigration from China, each unrelated to one another. Soto Zen’s history is notably different, but fairly convoluted in its own way, since it has two founders.

This concept of two founders started in the 19th century, after certain Soto Zen temples got into a spat about who was the actual founder of Soto Zen. If you’re reading this and know something about Japanese Buddhism, you might think that the answer is obvious: duh, it’s Dogen since he was the one who went to Song-dynasty China, and brought the tradition back. That was Eiheiji temple’s position at the time.

Conversely, Sojiji Temple took the position that it was Keizan’s influence a couple generations later that actually allowed it to flourish in Japan, establishing it as a proper sect, and not just an isolated temple. Further, until the 19th century, Dogen’s writings were kept secret, so very few Soto priests and students ever read it. So Dogen’s actual influence in the sect would be thus smaller than expected. Or so the argument goes.

Needless to say, eventually the two groups came to a compromise and agreed that both monks contributed to the growth of Soto Zen in Japan, each in their own way. Thus, in the Soto Zen tradition since, they are known as:

• Dogen – “high founder” (高祖, kōsō)
• Keizan – “great founder” (太祖, taisō)

Thus every 29th of September the Soto Zen liturgical calendar holds a memorial service for both founders known as Ryōsoki (両祖忌, lit. “dual founders memorial).

Even today, if you look at a Soto Zen obutsudan in Japan, you often see altar images like the ones linked here and here: namely an image of Shakyamuni Buddha in the middle, and Keizan on the left (facing right), and Dogen on the right (facing left). This is not an entirely unusual arrangement, by the way: in the Jodo Shinshu tradition, the Buddha Amida is in the middle, and often flanked by Shinran the founder, and Rennyo the restorer. Sometimes in Tendai Buddhism, you also see Shakyamuni Buddha flanked by Saicho the Japanese founder, and Zhi-yi the original Chinese founder.

The concept of “trinities” often appear in Buddhism, though not in the Western-Christian sense.

In any case, I am glad to see that Soto Zen was able to reconcile this dispute in a way that feels harmonious to me. I have visited Sojiji a couple times over the years (since it is thankfully pretty close to my wife’s house),¹ and it is a pretty neat temple. I haven’t visited Eiheiji yet as it is in a remote prefecture in Japan, but I am sure it’s quite a nice place to visit. Just like Keizan and Dogen, each temple enriches the Soto Zen community in its own way, and this helps broaden the community and make it more inclusive.

It is tempting to look at Japanese-Buddhist history and assign one sect to one founder, etc, but both Soto Zen and Rinzai Zen have histories that tend to defy this mold, and it’s important to recognize that religious history is organic and complicated, but also quite fascinating.

P.S. Moving back to two posts a week, now that the backlog is caught up.

P.P.S. Posting late, sorry! Made a scheduling mistake. 😅

¹ The present location of Sojiji is actually fairly recent. It was in Fukui Prefecture (same as Eiheiji) for many centuries, and was a branch temple of Keizan’s main temple of Yōkōji (永光寺). Ironically, as Yokoji declined, Sojiji gained in prominence. But, history is funny this way.
