There is no such thing as opposites. All things are what they are. The situation is different, but not opposites. Everything is itself and acts or is different. The point of zero is set to our existence and functional within our existence, but that zero may be -100 at another point of existence. We didn't set the points of existence, it set us. For example: The earth and everything that exists existed prior to our existence, or did it. Our existence existed, but wasn't in this place of existence in this form because it wasn't conditioned for our existence until we became of existence. Then and only then did our existence into existence in this form become knowningly there as self evident that we existed. This means that our existence was made and is here because existence made it possible for our existence. Our existence is a changed state of existence which allowed our existence and when things change radically enough our existence will be changed again to be non-existence or changed existence. This means there is no zero set by us and thus you cannot have an opposite. You can only have a condition, a changed condition that is going to change and thus the only permanence to existence is change. The existence itself is a changing existence and our existence is changed and different. A billionth, millionth, trillionth and on and on would have to have an opposite if there was such thing as an opposite. There is no opposites because we don't know the beginning and end. Everything is what it is. Everything is changing, so everything is different and is not based on it's opposite, but based on the conditions of its existence in this infinite world of change. That's the beautyand the fundamentals of existence. Everything is what it is and opposite to nothing. That is the opposite. NOTHING is opposite to something. Everything just is. What is it? What ever it is when you ask.J. Stallings - http://lawsofreality.blogspot.com/~See the truth~ It's right in front of you.
