The strength of gevurah relies on the ability to restrain oneself. “He that is slow to anger is better than the mighty; and he that ruleth his spirit than he that taketh a city” (Proverbs 16:32). Yet, restraint of ourselves is key, not only for the benefit of our soul, also for the sake of being in a position to offer diplomatic relations to those who enter into conflict with us. Another effective saying to keep in mind is that “he that is slow to anger appeaseth strife” (Proverbs 15:18). We would do well to learn from the wise words of King Solomon, for our hearts are heavy with the burdens we face; yet, too often, we are tempted to respond to others in a reactive way, rather in a manner of restraint.
If I may further explain, by way of a concrete example too rampant today. We might have fallen prey to the divisiveness that permeates society, dividing people into subgroups of us and them; the bitterness that festers as a result of demonizing the other, will only further the perpetuation of the lack of harmony in our lives, especially when our thoughts and rhetoric approaches the vitriolic. Being critical of others, through an excessive expression of gevurah, has the potential to devolve into the creation of newly marginalized classes of people in society, that may be increasingly demonized through generalizations. In this manner, tyranny rules the heart (G-d forbid).
