The primary difference resolves into something like a distinction of subject and object. This describes the way that an experiencing precipitates around a mark in the medium, which is no medium at all. Call it subject and object, because an experiencing requires an experiencer and an experienced. The whole is a unity of the three parts. It is what is here and now. The experiencing is a complex unity, prior, it has the principle of motion within it, it initiates. To say prior is not to mark a distinction on the same level. This way of speaking is alternative to a language of self reference, but has its own assumptions and limitations. It opens up a duality, subject and object are relative terms and can shift or reverse; what used to be the subject can be the object, and vice versa. This is not as simple as it sounds, and is not known in the fully precipitated elements, but is present in the peripheral awareness of process.
