Beware your own power

Beware your own power is both a warning to Mary and a rule she discovers how to enact: she has influence, even when she feels constrained, and that influence can hurt another person. The phrase links a brief admonition that no one is powerless to Mary’s later recognition that her own unhappiness can become a force in her relationship with Jamie.

Formulation and Meaning

A man tells Mary, “Remember, Mary. Beware your own power. No one is powerless.” The two sentences hold a caution and an assertion together. The warning does not deny Mary’s agency; it asks her to recognize its reach. At the same time, the assurance that no one is powerless makes power seem widely available, rather than the exclusive property of people with obvious authority.

The rule’s importance lies in this tension: having power is not the same as being free of constraint, and exercising power may carry a cost for someone else. The warning anticipates the way Mary will find an available means of influence not in a formal position or open confrontation, but in the emotional effect she can produce in Jamie.

Mary Recognizes Her Leverage

After reading something Jamie has written without laughing or smiling, Mary sees that her expressionlessness affects him. He looks hurt and asks whether she has to read the whole thing. Mary goes to her room appalled by what she has done, but concludes that she would do it again. What matters to her is the discovery that she has a power and should use the only one at her disposal: the power to make someone feel bad.

Mary’s thought that life is losing its edge accompanies this discovery. She wishes life would become interesting, yet finds it inert; she also reflects on the recurring stretches when she goes a little mad, and on the prospect of a longer change associated with age. Her account connects private experience to a broader sense of women as people who live beneath the visible surface, enduring a submerged tempest rather than simply displaying it. This reflection does not cancel the personal force of the rule: it gives Mary’s newly recognized power a context of constraint and interior pressure.

Enacting the Warning

Mary makes Jamie feel bad by feeling bad herself. She concentrates on that feeling until it seems pure, then comes to regard its use as obvious and even admirable. Her withdrawal becomes legible through repeated gestures: when Jamie speaks casually, she stares at him for several seconds and turns away; when they meet in the passage, she stops and holds her ground, daring him to cross what she experiences as a force field.

The effects become explicit when Jamie asks what is the matter with Mary. She feels exultant at what she takes as an open tribute to her power, and returns to the doorway. The rule therefore ends not as abstract advice but as a practice Mary has tested: she can use her own distress to alter the emotional atmosphere around her and make Jamie feel its weight. The scene preserves the warning’s caution even as Mary experiences the discovery as invigorating; her power is real, but its immediate form is the capacity to wound.
