If you knew it, you are peculiarly situated: very near happiness; yes, within reach of it. The materials are all prepared; there only wants a movement to combine them. Chance laid them somewhat apart; let them be once approached and bliss results.
Chapter 19 · Edward Rochester
Context
Still in disguise, the 'gipsy' tells Jane that happiness is within her reach and that only a single action is needed to bring it about, though Jane herself does not yet realize this.
Analysis
Rochester uses the passive construction 'the materials are all prepared' to make Jane's future happiness sound like an inevitable chemical reaction—all the reagents ready, just waiting to be mixed. This removes agency from both parties and casts their union as something fate has arranged rather than something he is actively engineering through this very deception. The vague gerund 'a movement' makes the necessary step sound effortless, masking the actual complexity and risk involved.
Essay Tip
Support a thesis that Rochester's rhetoric here is dangerously wish-fulfilling—he describes their relationship as if it were already sanctioned by Chance, a convenient narrative that lets him ignore the real obstacles (his existing marriage) that will later explode this 'bliss.'
