This means that she knows when to withhold as well as give. A *good* mother knows when and how to wean her child because it's time to nurture them with solid food. A good mother knows when to let them cry rather than running in to comfort them because this helps them grow. She even knows, when the time comes, how to discipline her child, quietly, patiently, firmly. She understands that her children need limits and rules and regular time tables.
While the Emperor's organization is external, the Empress' is intenal, but she is just as organized in her own way. She is connected to the Earth and the seasons and, when upright, certainly knows when it's the right time to do whatever needs doing; like a mother bird who knows when it's time to push her chicks out of the nest. She keeps to a softer but no less regular schedule. This means she will do what's right and necessary to help her child grow, even the things which seem cruel.
