Manifestation

We can have endless, amazing understanding in this absolute Essence of Being; we can describe some of its qualities; but we never feel we have described it because it is inexhaustible. It is the source of all qualities, all possibilities, and all potential; but when we experience it directly we find absolutely nothing. It is a delightful nothing that dazzles and releases. In other words it is the unmanifest source of all manifestation. From this source, everything appears as itself, originating from this unfathomable emptiness, but nothing becomes anything. (The Point of Existence, pg 424)

Manifestation turns out to be nothing but the differentiation of pure presence. Pure presence, a homogeneous manifold field, structures this manifold by differentiating it into the various forms of manifestation. Manifestation is not something that comes out of true nature; rather it is true nature that spontaneously structures itself into the myriad forms constituting manifestation. Thus it is said that manifestation is coemergent with true nature, a state referred to traditionally as nondual reality. It is nondual not because it is two making up a unity; rather it is primordially one, one field with inherent patterns that we recognize as the forms of manifestation. (Inner Journey Home, pg 297)

In other words, manifestation is the appearance of forms that the dimension of pure presence assumes, due to the flow of the logos. Yet manifestation is never separate from the absolute, for it is its radiance. Therefore, manifestation always has a ground composed of both pure presence and absolute, being and nonbeing. (Inner Journey Home, pg 437)

More precisely, the absolute has no relation to manifestation, for the possibility of relation does not arise unless there is differentiation. It is a matter of complete unity, absolute nonduality. (Inner Journey Home, pg 439)

Ultimate ground of manifestation

And since in actuality there is always manifestation, there are always presence and emptiness. We can say only that emptiness does not exist on its own; for it is always the emptiness of manifest forms, always associated with manifestation. There is no such thing as emptiness on its own, nonbeing on its own, without being. In other words, presence and emptiness together are in actuality the ultimate ground. And experiences of dissolution of presence in emptiness until there is total annihilation can only be an individual experience, for the world continues during one's annihilation. Therefore, we call the synthesis of presence and emptiness the quintessence, the deepest core and nature of everything. This does not contradict the truth that emptiness is the ultimate essence because it is the inner aspect of the quintessence. It only points to the fact that the underlying ground and nature of manifestation is always presence coemergent with emptiness. (Inner Journey Home, pg 437)
