These three aspects, Space, Personal Essence and Essential Self, are the most central aspects of Essence. In the process of inner realization they, in some sense, replace the self-image, the separate individuality of ego and the sense of self of ego, respectively. Most traditional spiritual teachings can be grouped according to which of these three aspects they emphasize. Buddhism emphasizes Space, the prophetic tradition emphasizes the Personal Essence, and most of the Hindu systems emphasize the Essential Self, which they term the "atman."

We see that the sense of spaciousness that results from the dissolution of boundaries is a real lived experience when the person's capacity for awareness is developed and refined. It is closely connected with the physical body. It is not abstract or metaphorical. It is as a real as experiencing one's own body.

Yet this experience of unity still contains subtle concepts that are difficult to discern. As we investigate emptiness more thoroughly, we can uncover more subtle and hidden senses of self. One of the concepts implicit in this mystical unity of appearance—where everything is pure presence and awareness that is the radiance of emptiness—is the concept of space. That is to say, even though everything is unified, even though everything is at once Being and nonbeing, even though everything is a manifestation of the same Beingness, there are still concepts of here and there. There is a here, and a there, and some distance exists between here and there. When the concept of space is finally recognized and penetrated, we understand that emptiness is not a medium. In other words, emptiness does not have spatial extension—there is no here and no there. Here and there are the same spot. Here is there, and there is here. As long as a measurable distance exists between the two, there is a concept of space. I don’t necessarily mean that spatial extension disappears in terms of perception, because manifestation always manifests in space. What I mean is that spatial distance disappears in terms of a felt sense, because true nature is beyond space. This no-distance realization can even be perceptual, but this is a further subtlety that we will consider later.

Whenever we become free from our identification with any self-representation, we experience ourselves as free from the structure patterned by it. This always manifests as some kind of space, as an inner field that feels exactly like empty physical space, but it is a state of consciousness a pure manifestation of Being.

There is a definite relationship between working through ego structures and the arising of inner spaciousness. This manifestation of true nature expresses its absolute dimension, with its emptiness. Inner spaciousness is not the same as ontological emptiness but is related to it in some mysterious way. The point is that because of this relationship, inner space stands for the total openness and lack of determination of true nature. True nature is ultimately formless, and hence any fixed or rigid structuring, as happens in ego development, is antithetical to it. In other words, ego structures, through their self-representations, specifically obstruct the ultimate indeterminacy of true nature, barring from the experience of the soul the aspect of inner space. More specifically, identifying with a self-image automatically blocks inner spaciousness. Therefore, when the soul finally understands a self-image and does not hold on to it, space arises.

Space is lost as the mind takes self-image for identity. We have seen that this leads to the building of boundaries in the openness of space. The final result is that instead of the experience of Being without mental images, one ends up with a mental image for an identity. So instead of space being pervaded by Being it gets filled with the self composed of many self-representations.

Space brings about expansion in the qualities of our senses, our sensations, and our mental capacities. It deepens our intuition. It expands our awareness into new dimensions of ourselves, some we would never have conceived could exist. It brings new capacities for perception and experience. In addition, space has the surprising and powerful capacity of expanding itself, continuously increasing the openness and dissolution of boundaries, allowing ever-greater understanding of ourselves and our minds.

We find out, as we penetrate our representations of reality, that space is a facet of Being. It is the openness of Being, or the open dimension of Being. We also discover that space is not only a manifestation of our being, of our true nature, but that it also deals directly with the question of representations. So space is the facet of our true nature that specifically and directly deals with the barrier of representations. The work on becoming aware of representations, seeing through and being free from them, has to do with the understanding of space.

Not only does space correct the distortion of body-image and dissolve the psychological boundaries of the self-image, it ultimately dissolves the self-image as a rigid structure bounding experience. This provides a hint regarding the ontological truth about self-image. Since we see that space makes the body-image objective and realistic, i.e., correcting it according to objective reality, we can assume that it also corrects the self-image according to objective reality. That is, ontologically, self-image is simply boundaries frozen in space, frozen by their cathexis with libidinal energy. When the cathexis is undone, the boundaries dissolve into empty space, which is what actually exists as the nature of the mind. Therefore, we can say that pursuing the psychodynamic understanding of the self-image all the way to the end will leave us with, among other things, a real and objective body-image and the experience of mind as open space.

Space always manifests in one's consciousness as the self-boundaries disintegrate. We can say either that space melts away boundaries or that the dissolution of boundaries allows space to manifest. It is one phenomenon. The dissolution of boundaries cannot be separated from the emergence of space. So here we see the role of space in inner change: there is no lasting change without a change in self-image. There is no change in self-image without the dissolution of self-boundaries, and there is no dissolution of boundaries without the action of space.

When we transcend the transcendence of space from finitude to infinity, when we are truly free from the concept of space, we realize that there is no here and no there and no everywhere. There is simply no location. I call this experience of no space “total nonlocality.” Nonlocal usually means that one is not located here but located everywhere. Total nonlocality means something different. It means that there is no extension and, thus, no space. It is experience without being here, there, or everywhere. There isn’t an everywhere to be. So what is present if there is no here and no there? We are back to the simple experience of the lizard—pure perception. We are back to simplicity before conception. This condition of total nonconceptuality is free both from the concept of space and from the freedom from the concept of space.

There are further consequences to the understanding of emptiness as non-being, which takes the enlightened awareness to new mysteries. For instance, in the perception of the unity of reality, in which everything is at once being and non-being, there can remain the perception of “here” and “there.” There are here and there, and distance between here and there. When we penetrate the concept of space, there is a feeling of no here and no there. We recognize that emptiness is not a medium. Non-being does not have extension; it is not a medium. We sense that here and there are one single spot, that here is there and there is here. Space does not disappear in terms of perception; as long as there is a distance between here and there that can be measured, there is a concept of space and a perception of space. Even if space as extension is perceived, in the realization of non-being it disappears in terms of a felt sense. Manifestation always manifests in space; True Nature is beyond space, and our realization can reflect that.
