Dave Bonta's short poem pictures a person on a beach, and it treats the body less as something separate from nature than as a part of it. The sand is white, the body is simply there, and the poem says it has been "made sweet" by "the easiness of nature." That phrase suggests a kind of relaxed, unforced contentment, as if the body has absorbed the calm of its surroundings.
The comparison to "land dissolving in the sea" deepens this. The edges between body, sand and water seem to blur, and the speaker appears to enjoy that loss of boundaries rather than fear it. The last lines introduce an "oyster-woman," whose "way / forever is to eat." Judging by the imagery, she stands for a life of plain, steady appetite, taking in the sea's gifts without fuss or guilt. The mood is sensual, unhurried and quietly celebratory, with a sense that living in the body can be simple and pleasurable.
