I'll see your Bodhidharma and raise you a Hui Hai (dont know why since I dont see whats to assert or negate)
Q: What does it mean when the sutra says: "The sound of discussion has ceased, and the role of thought is done"?
A: Words are used to manifest the doctrine. After understanding the doctrine, then, words are useless. The doctrine is void, voidness is the Tao, and the Tao is without words. This is the meaning of "The sound of discussion has ceased". Since the real meaning of the doctrine does not give rise to a single thought or perception and because no thought or perception arises, it is unborn. Furthermore, because it is unborn, then the fundamental nature of all forms is void, Next, since the fundamental nature of all forms is void, then everything in the world is non-existent. Finally, since all things are fundamentally non-existent, "the role of thought is done".
Q: Is the awareness that form is void and that the worldly is holy the same as Sudden Enlightenment?
Q: Just what is the meaning of "form is void and the worldly is holy"?
A: The mind defiled is the same as form, but the mind undefiled is void. Similarly, the mind defiled is worldly, but the mind undefiled is holy. To say it in another way, the Absolute Void mysteriously exists as form, but because its "form" cannot be grasped, it is void. Here, when we refer to "void", we are speaking of the voidness of Self-Nature. We are not referring, in this instance, to the voidness which occurs after the destruction of form. Similarly, when we refer to "form", in this context, we mean the form of the void-nature of the Absolute Void; but we are not speaking, in the usual sense, of form that creates other forms.
I can also quote a famous pop zen teacher (advaita) but the subforum has not been created yet.
