Existence is life, never ending and ongoing, forever and ever eternal. Using television as an analogy, the picture we enjoy seeing, the progression of a storyline with characters acting out a script, is but a trick of perception. You adjust the vertical hold on your set, not to remove strange bars appearing in the picture, but to place all screen activity within the range of your own perceptual preference. Your mind connects the electron dots into the picture images you think you see, while it totally ignores the true reality of what actually undergirds the operation. The way television operates, at least in our daily experience of it, is an illusion.
Existence is a lot like television.
What exists, what really exists, can't be fathomed by how it appears to operate or what it seems to be.
