CXCVII explained
Descartes argues that the mind is so constituted that mere bodily motions can excite all sorts of sensations and thoughts in it, without any resemblance between the motions and the ideas they produce.
What happens
Descartes argues that the mind is so constituted that mere bodily motions can excite all sorts of sensations and thoughts in it, without any resemblance between the motions and the ideas they produce. He uses the examples of written words and a sword cutting the skin to illustrate how different motions give rise to different passions and sensations, such as pain, color, sound, odor, and taste.

Key passages
“the motions of the body alone are sufficient to excite in it all sorts of thoughts, without it being necessary that these should in any way resemble the motions which give rise to them”
Bodily movements can generate any kind of thought in the mind, even if the thoughts do not resemble the movements at all.
Core claim of the chapter about mind-body interaction.
“the motion merely of a sword cutting a part of our skin causes pain, [but does not on that account make us aware of the motion or figure of the sword]”
The simple motion of a sword cutting our skin produces pain, without giving us direct awareness of the sword's motion or shape.
Example illustrating that sensation does not resemble its physical cause.
