If there is one, then it follows that there are two. There can never be one; there can never be only a subject, only an object. A subject cannot exist without an object. All things exist in relationship to something else. If there's an ox, then there is a person, and if there is a person, then there is an ox. Neither are in the eighth picture, neither exist. One is the subject, the other is the object. They must exist together. They cannot be without each other.

Who experiences this self-nature? It can only be experienced by someone who has left behind his self. If there is still self-nature to be experienced, that is not true self-nature. Self-nature is explained only to those people who haven't experienced it. For the person who has experienced it, there really is nothing to speak of.

Let's return to the analogy of the swimmer. When the swimmer is separate from the water, the water exists for him. But when he becomes one with the water, when he is the water, does the water exist for him? If he is the water, can the water have an existence of its own?

If "you" are "it", is this one or two? On the surface it looks like one, because you are it, and it is it. There is only one "it." But how can you know that there is "one" unless there's a second entity observing it. As I said before, if there's one, then there is definitely two.
