Thunder leaves the groundEnthusiasm
Excitement is good — provided it lands on preparation.
Yu means both joy and preparedness. Thunder bursts from the earth; a swell rises from underground and everything wakes. This ignited state is precious and perishable — enthusiasm will not wait; if you do not build the structure while it burns, it disperses faster than it came.
A line warns: proclaiming one's delight brings misfortune. Speak the excitement too early and the strength leaks away in words. Another line: firm as a stone. Joy and steadiness do not conflict; the best state is a drum in the chest while the hands lay the foundation.
Practice Ride this surge to finish the dullest preparation today. Enthusiasm only counts when spent on the unglamorous.
