If the opposing sides of a contrast meet, they cancel out each other. Therefore, when all opposite sides meet, you cannot perceive yourself as someone definitive. Hence there is nothing to hide what always has been and will be, namely the formlessness of oneness. The graphic is grabbed from the web.
According to science, two worlds were about to evolve in the milliseconds after the big bang: one of matter (the one we believe in seeing) and one of antimatter. But matter and antimatter cannot coexist. If they meet, an incredible amount of energy is released, and they disappear in one big flash.
Hence the brain excludes antimatter from our awareness, so we only experience a tangible universe defined by time and space. That is why science cannot find it, although it must be somewhere, according to their observations of the universe.

If contrasts are not kept apart to experience one part of it at the expense of the other, they annihilate each other in one big flash. The graphic is grabbed from the web.
However, the world of matter also consists of contrasts, like black and white, which cancels out each other if they meet. That is why you focus so much on the black letters that the white background is almost excluded from your awareness. In other words, not keeping black away from white, they meet and cancel out each other, and you are in a state of not-knowing.
Should you want that you can use hack #3.1 Inclusiveness is freedom to cancel out contrasts. But there are also other ways. For example, defocusing, see Defocusing cancels out contrasts, thus duality. In the below box, you can see different hacks for cancelling out the opposing sides of contrast.
When you defocus, contrasts fade out. Hence the brain cannot fabricate an illusion of something definable. The graphic is grabbed from the web.WAYS TO CANCEL OUT CONTRASTS
If you do not believe to be someone definitive, but you pretend to be it, what you appear to be makes no difference. You can read about this in hack #1.3 Pretending to be someone definitive is liberation.
Seeing everything as symbols of the fomlessness of oneness cancels out contrasts because the apparent differences are not perceived to make a difference. Read more about this in hack #2.1 Everything experienced is a symbol of oneness.
The more you connect with the empty breath, the more you become indifferent to differences. Thus contrasts are slowly but surely cancelled out. See HACK #5, A state of not-knowing is nothing but bliss.
Being alone together, the beholder sees no difference between the experienced and the experiencer. Consequently, time and space stop making sense, wherefore there is nothing to hide reality is the formlessness of oneness. See hack #7.1 Alone together, we go home.
You can also choose to go with the interaction of the opposing parts of a contrast. That will eventually make you feel so complete that disparities disappear, thus contrasts. See hack #4.4 The duality flow goes to non-duality.
NOTE: This article is part of hack #3.1 Inclusiveness sets you free from duality.
