Six at the beginning means:
At a time when all elements are pressing for progress, we are still uncertain whether in the course of advance we may not meet with a rebuff. Then the thing to do is simply continue in what is right; in the end this will bring good fortune. It may be that we meet with no confidence. In this case we ought not to try to win confidence regardless of the situation, but should remain calm and cheerful and refuse to be roused to anger. Thus we remain free of mistakes.
