The Void as ‘Not-Is’ – Direction

"Oh good man! If a person says: ‘The place which one can point out is Void', know that the Void is something non-eternal. Why? We have four directions to point out. If there are the four quadrants, know that the Void, too, must possess the four directions. All that is eternal has no direction to point to. To have directions means that the Void, therefore, is non-eternal. If non-eternal, is not away from the five skandhas. If someone were to say that certainly there is separation of the five skandhas, there would be no place to (it) exist. Oh good man! If anything exists by causal relations, we can know that such a thing is non-eternal. Oh good man! For example, all beings and trees stand on the ground. As the ground is non-eternal, what stands on the ground is, therefore, non-eternal."
