"This sentence is false" is the simplest proof that language and therefore, thoughts, can break ... but reality can't.

And so, from those 2 points, we have proven that thoughts ≠ reality and that reality ≠ thoughts. That's why there will always be a mystery with reality.

Can reality be grasped? No, it can't, but you can try to... if it's fun to you to try 😁
