Some forms of emptiness…
The emptiness from impermanence. The world of form is flux, always dying as what it is and reborn as something else. As soon as it is reflected in ideas, images and thoughts, it has moved on to something else. There is nothing fixed here. All forms are empty of anything that is fixed, permanent, anything that can be labeled and stay true to the label (not that it could even if it was fixed).
The emptiness from interconnectedness. Existence is a fluid seamless whole, with no inherent boundaries anywhere. Anything we differentiate out is inherently absent of separate existence. It is just a temporary local manifestation of the whole.
The emptiness from absence of I. There is no separate I inherent anywhere, no I and Other. There is only the appearance of it, coming from a belief in the idea of a separate I, placed on a segment of the world of form. For us, this sense of I is typically placed on this human self. Since this field of seeing and seen, of awake emptiness and form, is functionally connected with this human self, and this human self is a perceptual center for this field, it becomes the most natural candidate for being an anchor for this sense of a separate I.
The emptiness of awakeness. Awareness is empty, and the content of awareness is no other than awareness itself. So awake emptiness and form is inherently empty.
Before this is an alive experience, it cannot so easily be conveyed. But when this awake emptiness notices, and awakens to, itself, it is obvious.
Awareness has no form, is not finite in space and time, is timeless and spaceless, is that which all forms arises within, to and as, is not touched by the always changing forms, is no different from its own content.
It is empty of substance, empty of change, yet is also any substance arising and any flow of change. It is similar to a hologram in that there is form, but these forms are empty of substance. There is just crystal clarity there, empty awake crystal clarity temporarily arising as always changing form.
It is its own subject and object, it is the seeing and the seen, the field of awake emptiness and form.
And just about impossible to talk about in any way that makes sense if this is not already alive in awareness, if awareness has not awakened to itself as awareness, empty awakeness and form.
There are also the existential forms of emptiness, those arising from and within a context of a sense of I. These are the emptiness of longing, of a sense of something missing, of lack. And this emptiness is no other than a reflection of the emptiness of Existence, the emptiness of awakeness.
The existential emptiness can only be resolved, completely, when the emptiness of awakeness awakens to itself, becomes familiar with itself, allowing any sense of a separate I to dissolve, and seeing that it is also the fullness of all form.
By finding ourselves as nothing other than awake emptiness, any sense of I and Other falls away, we are filled up by the world of form, and find ourselves as nothing other than the fullness of the world of form. The world of form is no other than awake emptiness, inherently absent of any I and Other, and that is what we already and always are.
Even as we misidentify with a segment of Existence, there is also the (subconscious) knowing that we are awake emptiness and form, inherently absent of I and Other. And this discrepancy is what gives rise to the longing, the feeling of lack, of something missing. Something is missing, and that is to wake up to ourselves as always and already this field of awake emptiness and form, where there is no I and Other anywhere.
This field that is temporarily and functionally connected with this individual human self and soul, which has this human self as a vehicle in the world of form, as a perceptual center, and this too inherently absent of an I. It is just the local manifestation of the field as a whole.
