Chapter thirteen of the Tanya explains why the evil inclination feels so much more powerful than the good one—and why that feeling is actually evidence that you are winning.
The Talmud in Tractate Berachot says that "intermediate people are judged by both natures." Rabbi Schneur Zalman makes a critical distinction: it says "judged," not "ruled." The evil nature in the benoni does not rule. It advocates. It is like a judge who states an opinion in a legal dispute—but the opinion is not binding. There is another judge who disagrees. And the final verdict belongs to the arbitrator.
Here is how it works inside the benoni. The evil nature states its case in the left side of the heart: "I want this pleasure. I need this distraction. That forbidden thing looks good." The thought rises to the brain. Immediately, the divine soul—seated in the brain and extending into the right side of the heart—challenges it. Two voices. Two arguments. Who decides?
The arbitrator is God. The Talmud in Tractate Kiddushin says: "If the Holy One, blessed is He, did not help him, he could not overcome his evil inclination." God intervenes by radiating divine light that illuminates the divine soul, giving it the edge. The benoni wins not through his own strength but because God tips the scale.
But—and this is the part that surprises people—the evil nature in the benoni remains at full strength. It has not been diminished. It still craves everything it ever craved. It simply has no authority to act. This is why the benoni feels like a fraud. He looks righteous from the outside, but inside he is seething with desires he cannot eliminate.
The Tanya says: that is exactly how it should be. "Even if the whole world tells you that you are righteous, regard yourself as wicked." This does not mean you are actually wicked. It means you should never forget that the evil within you is alive and at full power. The moment you relax—the moment you believe the war is over—is the moment you lose.
