The story you’ll hear

A blade (刃) held over a heart (心). Patience isn't passive — it's the active choice to not let the knife drop. The seal script form is visceral: you can see the blade edge pressing down on the heart below.

What the old dictionaries say

Memory trick

Great image, wrong history. In the old analysis 心 tells you the word is about the mind, and 刃 is there for its sound (rèn, close to rěn). Keep the knife over the heart as your memory trick.
