Abraham Maslow famously said, “If you only have a hammer, you tend to see every problem as a nail.” I use some variation of this a lot in conversation, almost always in a negative way — it’s easy shorthand for saying that others are narrow or deficient or unoriginal in their approach. In one stroke, it can explain why, for example, a manager seems incompetent, or why institutions seem so resistant to change. If only they had more tools.

I’ve been noticing in the last few months how easily this relates to Zen teachings — and teachers — as well. Some in the monastic system believe strongly that monastic practice is the only path to the heart of the teachings. Others place all their chips on the precepts, so that everything they like is seen as an expression of the precepts, and everything they don’t like is a violation. It all comes down to just that. Some who embrace koan study say directly and indirectly that koans are everything, or at least, if you’re doing zazen but not engaging koans, you’re missing half of your body.

And then there is the zazen-only school, which finds support in the teachings of Kosho Uchiyama-roshi and is (I sense) increasingly popular in the West. It feels strange to say this as a Soto Zen monk, but I’ve always been uncomfortable with this all-or-nothing focus on zazen. Maybe it’s the implicit suggestion that it’s a return to what the ancient teachers (Dogen, or Bodhidharma, or maybe even the Buddha himself) really advocated. But more than that, I think it’s my feeling (biased, I confess) that it’s not really challenging. The discipline of zazen is challenging, of course. Zazen itself is hard work; coming back to it is hard work. But too often, the rhetoric around zazen-only practice feels like wish fulfillment: this is why I got into Zen, and this is something I like, so this must be the only thing that has any value or carries any authenticity. Even if every cell in your body resists doing zazen, philosophically, at least for many, I think it’s easy to get on board with it. Other aspects of the tradition do challenge us, directly, on a philosophical level: a hierarchical student/teacher dynamic, bowing, ceremonies as expressions of “offering,” robes…. It’s easy to look at those practices that make us itch a little and label them as “extra.”

If I’m honest with myself about this, I can see that I’m no different: on some deep level, I’m pretty convinced that good posture, a “yes” attitude, and some serious culture shock are the keys to just about everything. It’s a pretty simple vision.

In the Soto tradition, the people formally known as “Zen masters,” or shike (師家), are not necessarily the ones with the deepest realization or the most expansive wisdom — they are the people with the greatest overall knowledge of the tradition itself, particularly of monastic life. They are experts in the monastic system; they are the guides of monks in training. In many cases, these people are selected and specially trained to be vessels of that knowledge. Some, by virtue of having acquired that knowledge through other means, are simply recognized as having that rank. Without a shike around, you cannot have a formally recognized training monastery. At least one person there needs to be that resource.

In a sense, then, the shike is a generalist. We need those people. But we also can’t all be them. Some of us, through temperament or training or our teachers, have nothing but a hammer. What to do with it?

One of my teachers is always encouraging young Zen priests to find their “second specialty.” (The assumption is that every priest’s first specialty is zazen. In the West, it’s not a stretch to suggest that most priests are, to varying degrees, experts in zazen. But in Japan, it’s different, so this suggestion of a “first specialty” is sometimes a kind of attack.) He is an expert — at this moment, perhaps the expert — on how to fold transmission documents. There’s a whole tradition around this one tiny thing, and he knows all about it. Every year, when they hold a precepts ceremony for hundreds of people at a time at Eiheiji, he’s there in a back room, teaching young monks how to properly fold lineage papers. If you’re like me, your first response might be, Who cares? But that’s the point. Nobody cares. And so he stepped up and became that guy.

In Japan, there is so much to this tradition, and there are so many priests, that this idea of a second specialty is just practical. As I’ve written about before, even talking about Buddhism is considered a kind of specialist track. Not nearly all priests do it; if there’s a need for it, they can call up the guy across town who has cultivated that skill. There are priests who are experts in transmission ceremonies, so that other priests don’t have to be. Some focus on baika (a kind of sutra-singing), shōmyō (an even more specialized chant-singing), copying sutras, writing dedications of merit, reading dedications of merit, composing certain kinds of half-mathematical Chinese poems, and about a hundred other things. Most don’t, of course — the vast majority of Zen priests are specialists only in conducting funerals and memorial services, and even then, not really experts. They know a basic form, and no one around knows if that’s right or wrong, and that’s enough to get by. But if they want to take up a focus, they can do so, and no matter how obscure or trivial it may seem, it will be appreciated by the larger community. In the same way that ordained practitioners are responsible for more of the minutiae of the tradition than are lay practitioners, among the ordained, some priests agree to know a lot about one thing so that the others don’t have to.

In the West, I think it’s more complicated. In larger communities such as San Francisco Zen Center, we find the model of the kesa expert, or the cooking expert, but in most centers, there is just one priest, so specializing can seem impractical. Often, be it a result of training, or one’s teacher, or one’s temperament, part of the response is to keep things very simple. Even for those with a wide knowledge — and appreciation of — the tradition, there are limits, in a small Zen center, to how much of that can be shared.

All of this is on my mind as we plan our family’s return to North America (to Halifax, Nova Scotia). I know what I would like to do. I would like to build a monastery, a place that is alive with practice by the local lay community, but with an engine fired by full-time monks and nuns. It’s not that I’m necessarily qualified to do this, by the way. I am not a shike. It’s just that so much of my training, and so much of what I would like to share with others, finds such a clear expression in that monastic setting. And it’s not that I want everyone to be ordained, or that I think the monastery is the only vehicle for the practice; it’s that I want to be able to point and say, “That! That’s what I’m talking about.” That, and I deeply, deeply love that life and that schedule.

But building a monastery is not realistic, not today. Even if I can find the path to that goal, I won’t arrive there tomorrow, or even in the next 10 years. So, how best to use the tools I have now, in the workshop I’m actually in?

I don’t know.

And I’m torn. So central to this practice is the teaching that in doing just one thing, we can express every thing. The whole thing. No one aspect of the practice is lacking — each is a full, wide-open gate. Zazen is full and complete, and through it, we can know the point of practice. If we do it fully. Bowing is the same. Sewing a robe is the same. Chanting is the same. Cooking is the same. Just by listening fully, I am saying what needs to be said, doing what needs to be done. I believe that. And so I am interested in this idea of a second specialty. I would like to see teachers take responsibility for just that one thing, whatever it is, and explore it so deeply that their investment in it makes them a doorway to something more.

But the other side is that there is something more, and it’s not measured only in depth — it’s also measured in variety and scope. Zazen is a full expression of the practice, but at the same time, there is much more to this practice than zazen. And when that doorway of the teacher opens, that’s what we should see: “Oh, this too. And this. And this.”

There’s a common belief in the West — and, to a lesser degree, in Japan as well — that the most authentic transmission of Zen is the one that is the most pared down, the one that keeps just the bare essentials. I understand that impulse. But I think it’s not enough to keep alive the parts that we like the most, or that we think have the most staying power. We also need to take a look at the parts that will die without our intervention. A hundred years from now, what will we have saved?

What is the hammer? And how, with these hands, do we wield it?
