A penetrating person or idea gets to the heart of the matter and has a strong impact. Penetration can also refer to physical objects piercing through other things.
When we say something penetrates our minds, we mean it's really getting inside and affecting us deeply. Think about a movie that makes you feel all the emotions – its ideas might penetrate your thoughts in a way that's hard to shake off. We use this word when talking about art, music, or even arguments: "Her words penetrated my defenses and made me think twice."
