Just because nothing cannot be intelligently comprehended (as nothing is beyond our bio-processor's coding) does not mean that nothing cannot be experienced. For example; consciousness is no-thing, not a 'thing', yet is fundamental. It is my present understanding that the great 'nothing', the Void, is not that. It is quantum Mind/Consciousness. There is no brain to excrete it's (waste matter) 'excrementation' (thought). There is also no memory capacity (that is strictly a temporal function), so ideas, thoughts, etc... are fictions within the dream.
Back to the 'nothing' that I make into my 'existence'. The 'nothing' is, as I mentioned, Mind. Mind equals the quantum field of potential/possibility waves. Bindu, the 'undifferentiated potential' of the Hindu sages. And quantum physics.
Consciousness (Will)(immaterial, no-thing) 'touches' upon these waves of 'potential' and one of all possible 'futures' manifests as a particular 'code'.
Our sensesory apparatus are receptors for this code. From receptors to brain where the information is 'decoded' into an internal hologramic mental image of our universes. We see, touch, hear what the information waves send. We use memory to decode and color and evaluate and judge and imagine sequence and linearity and time.
This is existence.
'Transcending existence' is
becomming that Consciousness/Truth through the diminution of egoically isolated self image. This site has some interesting reading and links.
Ego Death and Self-Control Cybernetics
Transcending existence is no more difficult than becomming 'lucid' within a dream. Ever have a dream that you were aware that you were dreaming? All of a sudden you had choices, eh? You could fly if you liked, have the neighbor choke on a bone, visit distant galaxies and cultures, etc.. Transcending (becomming lucid) the dream of discrete 'existence' in our day to day 'dream' (Enlightenment, salvation, liberation...), we become, once again, One Consciousness/Mind, beyond the dream of 'existence' and its attendant delusions, such as 'temporal existence'. One can 'deliberately' focus Consciousness on 'potential waves' (Mind) and affect the 'existence' thus produced ('the' universe). Exactly like the night dream! All the time knowing, of course, that the 'something' that I call forth from 'nothing' (Mind) is still, ultimately nothing (Theurgy, QM, Mysticism, Metaphysics, Creative Arts..)
Now, to tie this into the topic;
Yin/Yang represents the illusions and delusions of 'existence'; when 'existence' is transcended (when Self is realized experientially as OneConsciousness) the fictitious duality of Yin/Yang becomes, once again, merely a metaphor of the 'dream'...
Just a mental game where we can play in 'god mode', or slave mode, or....

I really wasn't intending to go into this here and now. Well, this is my current perspective, anyway, for what it's worth... and I just ran out of words tonight.
