Once, on a visit to the Los Angeles Museum of Science, I came upon a curious object known as a Mobius Strip. A Mobius Strip is essentially a loop, with a half twist in the surface. This half twist is the feature that gives a Mobius Strip it's most peculiar characteristic. It may look like a loop, but it only has one side and one edge. If you try to paint only one side of it, you will inevitably paint all of it. If you try and draw a line down the middle, of one side of it, you will end up drawing a line that meets itself; because it only has one side. If you try to color what looks like the outside edge, you will soon find yourself coloring the inside edge; because it only has one edge. The Mobius Strip gives you no choice about which surface to paint; because it only has one surface; this makes it the perfect metaphor, for the concept of choosing One-ness.
Choosing to see the One-ness of all things can be a very daunting task, if the mind is still filtering through the divided lens of duality. Years and years of conditioned thinking from a dualistic perspective, will not easily yield to a simple suggestion, that all is one. It is especially hard to see this, when the object you see is manifesting as aversion; something or someone you have no desire to be one with. We only want to be one with people or things, that pass a certain standard. Beauty, pleasure, joy, in all their variations are welcomed; ugliness, pain and sorrow are not. One-ness, like the example of the Mobius Strip, doesn't give you a choice, if it did it would not be One-ness. To choose, to make any kind of distinction, to show any preference intrinsically promotes the exclusion of one over another. Choice, distinction, and preference are antithetical to One-ness.
The elements of choice arise simultaneously, and cannot stand independently. There is no chooser, without a chosen; no chosen, without a chooser; and no choosing without both a chooser and a chosen. Eliminate any one of the elements and there is no concept called choice.
Where in One-ness is there room for choice? There isn't; there can't be. That would be like saying all leaves room for more. All means all; not less than, not more than. A circle has 360 degrees not 359, not 361. All is complete. One-ness is complete; it can't be added to nor subtracted from, and from this standpoint, gives you no choice. If there is no choice then, by logic, there is nothing to choose, not even One-ness.
Labels are all we have to express the inexpressible. Duality, non-duality, One-ness, choice, all are just labels; one more thing to cling to, one more thing to transcend. You can't choose One-ness because you are One-ness; you are an aspect of the Absolute One-ness, and so is every other person, and every other thing in all creation.
So, cut yourself a strip of paper; give it a half twist and tape the ends together. Take a highlighter and start coloring what appears to be a side. When you have finished coloring your, "chosen side", you will have colored the entire strip. There was no choice in the matter, there was only One-ness. Thank you, Mr. Mobius.
Peace be with you,
