The downward escalator of life[1]
הלא אם תטיב שאת ואם לא תטיב לפתח חטאת רובץ וגו’
Is it not that if you improve then you’ll cheer up[2], and if not, sin crouches at the door…[3]
The two sons of Adam, Kayin and Hevel, took two different paths in life. Kayin became a farmer, and Hevel became a shepherd[4]. At some later point, Kayin decided to bring an offering to Hashem[5]. He brought from the worst of the fruit of his land[6]. Hevel was also inspired[7] to bring an offering. Unlike his brother, he brought the best of his cattle[8]. Hashem accepted the offering of Hevel, but ignored the offering of Kayin. This caused Kayin to become depressed[9]. Hashem, as a form of encouragement, taught Kayin a lesson. He told him that if he improves, then he will cheer up[2]. However, if he doesn’t improve, then sin crouches at the door[10]. What does this lesson mean?
