Nothingness; the source, pure potential of all that has been, all that could become. Nothingness is available to every sentient mind; mindfulness and presence pull back the veil of our conceptual mind, revealing that thought, time, the separation of I and other, and myriad assumptions and opinions, are nothing but fallacies.
That nothingness, the great time—the infinite moment in time before the machination of neurons concoct another thought—is the abode of awareness, beyond the prisons of past and future, as these can only live in memory and imagination; tools of the conceptual mind. Nothingness, or awareness, or mushin, is a state of possibilities, a state still yet to settle on a decision, to forge information; every thought, every categorisation, every memory, every imagined point in the future, still in limbo. Not until the wavefunction of thought collapses do we see a decision—something discernible, information—the emergence of ephemeral entities like ideas, memories, and time.
To be mindful, present, in sadhana, is to sit in an experience of the superposition—all possibilities—of thoughts, an experience of the primordial nothingness before the dawn of time, a precursor to a Big Bang of thoughts. And like the cosmological Big Bang, which pried open existence, so, too, this wavefunction collapse to a single thought, a single decision, creates existence—the moment-to-moment existence of concepts and ideas. And yet, these concepts and ideas are annihilated at the next moment of mindfulness. Information is created, destined to be lost to the Universe.
The dichotomy of thought is that at once it is the wellspring of all concepts, all ideas, and yet also the death knell of the thing we humans prize above all else, peace. What is and what is not; what could be and what is not; division of self and other; categorisation of good, bad, and otherwise; so desperate to be true and correct, until shown to be temporary, annihilated at the next point of mindfulness.
And for peace to once again return, in the ceasing of information and concepts; the great time.
