WHEN calamities happen together, the form of consideration should be whether it is easier to take an offensive or defensive attitude. National calamities, coming from Providence or from man happen from one's misfortune or bad policy. The word vyasana (vices or calamities), means the reverse or absence of virtue, the preponderance of vices, and occasional troubles. That which deprives (vyasyati) a person of his happiness is termed vyasana (vices or calamities).
