Five short lines, and the title still manages to promise something grander than the poem delivers. "Spiritual teacher" sounds like a robe, a mountain, a hush. What we get is a man in a disco being bought by young women, and a final line in which his enlightenment turns out to be good for sex. The whole poem lives in the gap between that solemn title and that shrug of an ending.
The opening line is the only one that looks inward: "In my chest, a thin rain." It has no verb, so it reads like a weather report on the speaker's body. The adjective matters. A "thin" rain is not a storm of grief but a faint, persistent dampness, a low-grade sadness he doesn't dramatize. Rain is also a quiet image of cleansing and renewal, so the line half-suggests a spiritual condition while refusing to claim anything grand for it. Whatever the speaker feels, it is small and unresolved.
The second line moves the scene outward, repeating the opening "In" to begin a second location: "In the disco, the young ladies bought me." The word "bought" is the poem's hinge. A teacher is normally sought out or followed, but here he is purchased, like a drink or a ticket. The syntax is also passive in spirit, since things are done to him. The next line, "light for night," is the most open to interpretation. Because of the comma after "me," it can read as a description of what he has become, so that he is light (a glow, a diversion) for their night. Or "light" might hint at lightness itself, something weightless and easy to carry, and perhaps at a pun on "enlightenment." The line also holds a small internal rhyme, light/night, the only rhyme in the poem, and it sounds like a slogan or a neon sign. That is fitting for a line about being turned into a service.
Then comes the pivot: "I found my Zen / useful in bed." Here the line break does the comic work. "I found my Zen" could be the climax of a spiritual journey, the moment of arrival. The break lets that expectation stand for a beat, and "useful in bed" then deflates it. "Useful" is a deliberately flat word, the vocabulary of kitchen gadgets, and it recasts a discipline associated with emptiness and detachment as a practical technique. The joke is gentle but pointed. Spiritual language has been absorbed into the economy of the dance floor, where everything, including the teacher, can be bought and used.
The construction supports this. The three "in" phrases (in my chest, in the disco, in bed) trace a path from interior feeling to public space to private room, each step narrowing and cooling the speaker's distance from himself. There is no rhyme scheme and no regular meter. The lines run to five words, eight, three, four, three, so the poem seems to shrink as it goes, ending on its shortest, most casual phrase. A faint sound-link may be at work too: the short "e" in "chest," "Zen," and "bed" quietly ties the speaker's sorrow, his philosophy, and his bedroom together, as if they were one thing.
What keeps the poem from being a simple joke at spirituality's expense is that thin rain. If the speaker were merely smug, the first line would not be there. Its presence suggests a man who knows his wisdom has been reduced to a party trick and who feels, faintly but really, what has been lost. The humor reads as self-mockery with an ache underneath. The poem leaves open whether he is a fraud, a realist, or simply someone who has found that the only audience for his teaching is the one that pays.
That ambiguity is the source of its interest. In so few words, the poem raises questions about whether wisdom can survive being useful, whether being wanted is the same as being understood, and whether a person can be sincere and for sale at once. It doesn't answer them. It lets the rain fall and the lights flash, then ends on the most ordinary word it can find.
