Let's put it this way, "there's nothing really out there that is as we perceive it to be". The deeper we look into what appears material, the more apparent nothing we see".
Sort of like past, and future define time, but the NOW will never be pinned down.
It's ineffable. All of it. Like the hand pointing at the moon and everybody studying the hand. We use our five material senses and try to use them to get our head around an immaterial sense of being. It's like using a sledge hammer to saw a piece of wood. Wrong tool.
To me, NOW is all there is and it is eternal and outside of time. Eternal not meaning a very long time with seemingly no beginning and no end. NOW, always NOW is all there is. Outside of time and always present. The past is merely a story regarding nows gone by and does not exist except as an idea in the now. The future doesn't exist and never did. It is a projection of past stories into the future as an idea of what could be, but still, just another story in the now.
And even now, 10 people will read this and there will be 10 different understandings of what is said.
Rajneesh once said something akin to this. "I have a thought (meaning an understanding in a spiritual sense) and I come back and 90% is lost. Then, I put it into words, and 90% of that is lost. Then, you hear it, and 90% of that is lost......so why do I talk?
