It means that one should have lofty aspirations.
The husband should aim high, worship sages, abandon lust and doubt, so that the ambition of ordinary people can be revealed and felt; Endure flexion and extension, remove details, ask questions extensively, except being too stingy.

If the ambition is not strong, the spirit is not generous, people are mediocre and stagnate in vulgarity, silently bound by feelings, and forever dormant in mediocrity, it is bound to be indecent!
