@Frank Apisa,
If the people "arguing the other side" find their selves or minds as agents of action then, to that extent, they will see the "
mushin" or no-mind point of view to be wrong; but when they can no longer find their mind they will realize that they were deluded. There's nothing to argue about.
By the way, we conventionally use the phrase "losing one's mind" to indicate something bad. From the zen perspective there's no mind to lose. And that's "good" for when you realize your
mushin you also realize that since there is no "thing" (i.e., mind, self, ego) inside you, you
are the world, the world of sensations or experiences that comprise your worldview. You are your experiences; they do not happen to some thing within you. This realization of unity with the world is, eveyone who has the perspective agrees, a "good".
