"自分が嫌なことを他人にしてはならない。これがトーラー全体であり、残りはその説明である。"
— Rabbi Hillel
Simplified Meaning:
Imagine you dislike it when someone is rude to you. It makes you feel hurt and angry. This quote is saying that because you don’t like being treated this way, you should avoid treating others rudely. It’s about using your own feelings to understand how to treat people kindly and fairly. For example, if you wouldn't want someone to cut in line in front of you, then you shouldn’t cut in line yourself. This idea covers most of how you should act: treat others well, like you would want to be treated. The rest of the rules and teachings just explain this basic idea in more detail.
