But like all cards, this too has its more negative aspects- here, the warning is that uncontrolled or unsustainable growth can ultimately lead to chaos, and destruction. It can also be smothering, attempting to control everything in life, and instead of allowing for growth, it crushes it. So in its positive sense, this represents the fuel for growth and development. In its more negative connotation, it tells of excess growth; mutation, loss of structure and eventual chaos coming from rampant, unchecked expansion, or trying to control growth too much, ultimately stifling and smothering it.
Again, consider a plant as a metaphor of the relationship between these two halves- the nature of a plant is to expand and grow, yet it's where it doesn't grow that gives it the ability to survive. It grows stems and leaves to take in the sun, and roots to go deep to find water to keep it alive. In this way, we see the expansive force and also the restrictive force. Perhaps a better word for it than restrictive could be structuring; it gives the plant structure and shape. Were this plant too excessively restricted, it wouldn't be able to grow at all, and if its growth didn't fall into an order and pattern, and expanded faster than the plant could provide sustenance for, it would ultimately fail as well.
So the message of these two cards is to impose structure and sensible limitations, yet at the same time allow for things to unfold as they will. Often the power to direct the growth and change in our lives lies with each of us, and to govern that change and direct it to our own ends is within our own powers. Often it's simply a question of taking the reins, or taking the orb and scepter, if you'd rather, and guiding our lives in the direction we ourselves choose.
