7. To pierce the sky
While Wáng Dun was weaving a plot,
he dreamt that he pierced the sky with a tree.
Master Xu Fù explained to him:
"If one superimposes on the character tian: sky, the character mù: tree,
then one gets wèi which means not yet".
Thus, despite the apparent ardour of Wáng Dun to transpierce everything, sky included,
the latent content of his dream is a call for prudence:
"one should think before acting" concluded Xu Fù .
