Mezuza

Can I affix the mezuzah of a dead parent to my doorpost?

My mezuzah scroll came to me unrolled, in a vacuum-sealed plastic. My question is, can I roll up the mezuzah while inside the protective plastic... Or must I take it out of the plastic, roll it, and then put the plastic back on?

Can you explain the significance of having a mezuzah on your house and its power to guard the household, as opposed to it being just a superstitious belief? Thank you!

Dear Rabbi, I know that having a mezuzah is a mitzvah, but I don’t know much about its significance beyond that.

Dear Rabbi, I am making a needlepoint cover case for a mezuzah and there are two inserts available. One is hand-written, the other one is reproduced. Is there a religious difference, or just a price difference?

I’ve seen people kiss the mezuzah when leaving or entering their home. My question is: Why? Btw, I really enjoy the questions and answers you post in your weekly Shabbat Shalom newsletter. Thanks!

Hi Rabbi, does a bedroom need a mezuzah? Thanks
