Mencius - Book 2, Part 1, Chapter 4B

Confucius said, "Did not he who made this ode understand the way of governing?" If a prince is able rightly to govern his kingdom, who will dare to insult him?

'But now the princes take advantage of the time when throughout their kingdoms there is leisure and rest from external troubles, to abandon themselves to pleasure and indolent indifference; they in fact seek for calamities for themselves.

'Calamity and happiness in all cases are men's own seeking.

'This is illustrated by what is said in the Book of Poetry,

"Be always studious to be in harmony with the ordinances of God,
So you will certainly get for yourself much happiness;"

and by the passage of the Tâi Chiah, "When Heaven sends down calamities, it is still possible to escape from them; when we occasion the calamities ourselves, it is not possible any longer to live."'
