So what is already enlightened?
What already has no argument with reality?
When we sit with this question and let it sink deep within us, we may first notice the resounding silence. The mind may launch an argument right away, wanting an answer to the vexing question. We don't have to settle for mind's prattle. We can notice the silence in the background, and see how the silence holds mind's argument. We can notice that the silence is aware of mind's argument, and yet offers no counter-argument of its own. We can notice this everpresent silent awareness. Is there a moment when this is not?
Arguments start and stop; noise starts and stops, objects in the mind appear and then disappear. Where do they go? Where did they arise? What is present before they arise and after they go? Everything appears in the everpresent silent awareness and returns to it.
And what is the everything that arises within awareness? Can it be anything other than awareness taking shape as something? Can it be 'made of some other substance'? Can a wave be anything other than water in different shapes? But this is not something to be deduced in the mind. See this for yourself. Get to the root of everything that pretends to be other than awareness. Get to the root of every argument with reality.
If I take myself to be this body-mind, then clearly I was born at some time and I must die at some time. What did I come from and where do I go? Notice mind's insistence on this identification with the body-mind. Alas, even the mind is not happy with this identification. If it were happy with it, then you would not be reading this post, right? :-) So notice that mind believes what it does because it does not know any better. But something inside us remains unfulfilled by mind's reasoning. That is the doorway. Go there if you can. Simply occupy that unease with a curiosity to find out what it really is. Don't be afraid of it - it is grace waiting to be received.
This everpresent silent awareness has no argument with reality. It is already enlightened and it is everything. And this means it is I. The I that you are is already enlightened. And all the feelings of unenlightenment are only enlightened awareness in different shapes - free to play in complete freedom - so free that there is nothing to lose even in feeling unenlightened.
For this here is forever enlightened, beyond feeling and thought. And from this enlightenment it plays a darned good game of virtual reality, so real that it fools itself quite successfully - a remarkable feat in itself. And this miraculous self-delusion is seen through and a belly-laugh arises from deep within.
So in summary,
I notice the everpresent silent awareness, that is present before all thoughts and arguments and after them. I see that that which appears and disappears within the everpresent silent awareness is nothing but awareness itself in different forms. I see that this body-mind too appears in the everpresent silent awareness. I see that I am the everpresent silent awareness. Nothing that this body-mind does can be other than the everpresent silent awareness. And it is from this seeing, and from this freedom that I can drop the argument with reality.
The wave knows itself to be water and from this knowing it is free to be a tsunami or a lapping beach wave. From this knowing it is free to be powerful and to be overpowered as the case may be. From this knowing it can advance or retreat as it may happen. This is water living as the wave. This is enlightenment living as you and I.
