“Either you real or you ain’t”

The other day one of the teachers in our zendo gave a talk in which she likened the practice of zen to classical ballet: one of the most painfully demanding of disciplines. Dancers must show up for a 90 minute class every single day without fail, no matter how experienced and accomplished they are or think they are. Always showing up, always striving, tuning, preparing for the stage — that’s what it’s about. So it is with the Zen practitioner. You show up at the zendo for formal zazen as often as you possibly can, regardless of whether you feel like it or whether it’s convenient. Formal zazen is essential, a necessity. LIkewise, extended sittings such a as zazenkai and sesshin are not optional add-ons. They are what you do when you’re a Zen practitioner.
This idea was reinforced by a scene that I recently saw in an episode from the fifth season of the venerable HBO series The Wire. During a prison visit, the incarcerated father admonishes his son to apply himself with greater diligence to his work in the drug trade. Either you real or you ain’t, he says. Irony notwithstanding, this paternal advice underscores a valid point. The teacher’s talk was evidently aimed at students who she thought needed to hear it. She might as well have said, either you real or you ain’t.
I was reminded of something my family has said about me over the years: you are a fanatic, an addictive personality. When you set your mind to something, you go at it relentlessly, obsessively. I have always tended to think, well, ok. When they suggested that going away for a week-long sesshin last summer was an example of my fanaticism, I figured, whatever. Now I am not so sure. Sesshin is what zen practitioners do. Why do this at all unless you’re serious? Either you real or you ain’t.
Update
Looking at the above three months later, I see the fallacy in the argument “I am not a fanatic; sesshin is what Zen practitioners do.” Sitting in meditation several hours a day for a week is extreme — fanatical, even. Dedicated Zen practitioners are fanatics.
