Arthashastra
प्रायशश् च कोप वशा राजानः प्रकृति कोपैर् हताः श्रूयन्ते, काम वशाः क्षय निमित्तम् अरि व्याधिभिर् इति ॥
In a majority of cases, kings given to anger are said to have fallen a prey to popular fury. But kings addicted to pleasures have perished in consequence of serious diseases brought about by deterioration and improverishment.
english translation
