That means we have to find an individual who takes that position. The pair system is very important. Even if we are in the upper position we must keep the lower position in mind. If we are on the right side we must consider the left side. This is so that we can harmonize.
All creation lives for the sake of the other.
So at the time you say up, first recognize down, then recognize up. When you say right, recognize left first and then right. And in circular motion too, one moves for the sake of the other. Without this you cannot have motion. If one individual does not have the other in mind it will lead to destruction.
