אָמַר רַבִּי לֵוִי בַּר חָמָא, אָמַר רַבִּי שִׁמְעוֹן בֶּן לָקִישׁ: לְעוֹלָם יַרְגִּיז אָדָם יֵצֶר טוֹב עַל יֵצֶר הָרַע, שֶׁנֶּאֱמַר: ״רִגְזוּ וְאַל תֶּחֱטָאוּ״ אִם נִצְּחוֹ — מוּטָב, וְאִם לָאו — יַעֲסוֹק בַּתּוֹרָה, שֶׁנֶּאֱמַר: ״אִמְרוּ בִלְבַבְכֶם״. אִם נִצְּחוֹ — מוּטָב, וְאִם לָאו — יִקְרָא קְרִיאַת שְׁמַע, שֶׁנֶּאֱמַר: ״עַל מִשְׁכַּבְכֶם״. אִם נִצְּחוֹ — מוּטָב, וְאִם לָאו — יִזְכּוֹר לוֹ יוֹם הַמִּיתָה, שֶׁנֶּאֱמַר: ״וְדֹמּוּ סֶלָה״.
Incidental to the verse, “Tremble, and do not sin,” the Gemara mentions that Rabbi Levi bar Ḥama said that Rabbi Shimon ben Lakish said: One should always incite his good inclination against his evil inclination, i.e., that one must constantly struggle so that his evil inclination does not lead him to transgression, as it is stated: "Tremble, and do not sin."
If one succeeds and subdues his evil inclination, excellent, but if he does not succeed in subduing it, he should study Torah, as alluded to in the verse: “Say to your heart.”
If he subdues his evil inclination, excellent; if not, he should recite Shema, which contains the acceptance of the yoke of God, and the concept of reward and punishment, as it is stated in the verse: “Upon your bed,” which alludes to Shema, where it says: “When you lie down.”
If he subdues his evil inclination, excellent; if not, he should remind himself of the day of death, whose silence is alluded to in the continuation of the verse: “And be still, Selah.”
