"Trying to control the emotional self willfully by manipulative attempts is like trying to choose a number on a thrown die or to push back the water of the Kamo River upstream. Certainly, they end up aggravating their agony and feeling unbearable pain because of their failure in manipulating the emotions."

You may say a cat uses good grammar. Well, a cat does -- but you let a cat get excited once; you let a cat get to pulling fur with another cat on a shed, nights, and you'll hear grammar that will give you the lockjaw. Ignorant people think it's the noise which fighting cats make that is so aggravating, but it ain't so; it's the sickening grammar they use.
