"ma" means what and "na" means now (or sometimes please). I would translate it "what now?" or "what's this now?" or even "Wow, what's this new stuff?" Another expample of usage is "Shalom. Ma shlomcha (shlomech - for women), meaning "Hello. How are you?" or more literally, "Hello (peace). What is the state of your well being?"
Throughout history, people have been enslaved by a tactic called "bread and circuses" where they distract us and then, while you are celebrating all the cool free stuff you are getting, they do something tricky behind the scenes and pow, your freedom is gone. We must be careful of what we take from the government. It is somewhat like telling kids not to take candy from strangers. It is really that simple. Thanks for stopping in again. I really like your well thought out comments.
