That’s why the Gemara (Kiddushin 40b) says that ב∆ל∆ּכַל ה∆מֹוּ„ ּ̃וַּּׁ̆ב ל≈כֹו‡ָה – if a man eats in the street, he’s like a dog. Even if he washed his hands and he made a bracha, if he eats in the street he is domeh lakelev, he’s like a dog. Because a human being has to remember who he is and therefore he eats his bread in a different manner.
So if you walk in the street munching on a piece of pizza, you have to know where you belong, in which category.
The world today has forgotten the sublime principle of ם∆ח∆ל לַכ‡ֹּ̇ – You, Adam, shall eat bread. And so before we go on, let’s keep in mind what we have already gained tonight; and the next time you eat bread you have something to think about. It’s a demonstration of the greatness of mankind, that ם∆ל∆ˆּ¿ב ‡ָר¿בּƒנׁ∆̆ םָ„ָ‡ יבƒבָח – How beloved by Hashem is man, that he’s created in Hashem’s image (Avos 3:14). And it’s a demonstration of what’s expected of us. Our diet, bread and other foods instead of grass, is an eternal reminder of the greatness of mankind that must always be kept before our eyes as a foundational principle of the Torah.
