Eretz

Today's Hebrew word is "Eretz", also pronounce "Aretz" (though suddenly I am pulled magnetically to change this to "today's word is "tov", mistranslated as "good", so I'll do that one next)
Eretz: the land. In the beginning God (read as "the ceaseless creativity of the universe, whatever organizing force juggles or paints or mirrors this universe into being) created the heavens and the earth. The phrase, "the heavens and the earth", ha-shomayim v ha-aretz, can refer to "the spiritual world and the physical world", so "eretz" here means "the physical world". According to Judaism, the physical world is one tiny tiny fraction of the world. The vast vast majority is the shomayim part, the world of ideas, dreams, history, future, interpretation, spirit, fantasy, principle, emotion, thought, hope. Physical world? Tiny.
Eretz. Earth. Physical world. The word "eretz" also refers to the Land of Israel, Eretz Yisrael. You would never hear someone say they are "b'yisrael", in Israel. Only "ba-aretz", in the land. There are two places to be: ba-aretz, in the land of Israel, and ba-chutz la-aretz, outside of the land of Israel. Honest. People travel to "chul", a short form for 'outside of the land", and they come back to ha-aretz. They come back. They always come back. Even if it takes them 2000 years, they come back to the land.
Eretz: land
