The lower trigram, Xun, has wood as its image; the upper, Kun, means the earth. With this goes the idea that wood grows upward in the earth. This "pushing upward", unlike "progress" (hexagram 35), is bound up with effort, just as a plant needs strength to push upward through the earth. That is why the hexagram, although it is attended by success, is related to the effort of the will. "Progress" shows more expansion, "pushing upward" more of a straight ascent to power and influence out of obscurity and lowliness.
