קהלת, פרק ז׳, פסוק ט״ז

Life is complex and demands a careful balance. Even the pursuit of noble virtues, such as righteousness and wisdom, can become destructive if taken to an extreme. The guidance provided here serves as a natural counterweight to human tendencies, warning against the dangers of extremism [ביאור שטיינזלץ].

One primary perspective views this as a warning against elevating human logic above divine command. This does not mean a person should limit their good deeds, as there is no maximum measure for doing good. Rather, it cautions against trying to be more righteous or wiser than God and the boundaries set by His wisdom [תורה תמימה, מצודת דוד]. A clear example of this is King Saul. He believed he was acting righteously by showing excessive, misplaced mercy to the wicked when he spared the nation of Amalek. Saul relied on flawed logic, arguing that if God requires a sacrifice to atone for a single murdered person, it surely makes no sense to wipe out an entire population and their innocent animals [רש״י, תורה תמימה, צאינה וראינה].

Building on this idea, there is a serious danger in becoming so righteous in one's own eyes that one begins to question God's justice. Overthinking and relying too heavily on personal intellect can ultimately lead a person to heresy. This occurred with Job, whose intense feeling of personal righteousness led him to view God's judgments as evil, eventually causing him to deny divine providence and the resurrection of the dead [תעלומות חכמה].

Another perspective shifts the focus to daily behavior, warning against asceticism and overly strict living. A person should avoid forbidding things that the Torah has permitted just for the sake of creating extra religious boundaries [מצודת דוד]. This includes avoiding extreme practices like excessive fasting or praying continuously from morning until night [אבן עזרא].

The destructive result of such extreme behavior is total desolation [מצודת ציון]. When someone adopts excessive restrictions and separates themselves from normal life, they risk abandoning healthy society. They can become completely isolated, leaving them lonely and desolate because no one wants to associate with them [מצודת דוד, אבן עזרא]. Beyond this social isolation, extreme behavior can drive a person to madness and panic [ביאור שטיינזלץ], and ultimately result in eternal spiritual ruin [תעלומות חכמה].
