Holy!

Rebbe Akiva [Pesachim 112] says that when you walk into a home, even your OWN home, you shouldn't come in suddenly rather you should knock first. Where does he get THAT from??

AHHHHHH Rashi fills us in [based on the medrash]. Rebbe Akiva learns it from the kohen gadol who has bells that ring before he enters the Holy Of Holies [Kodesh Hakodoshim]. BUT WAIT!! Your home isn't the Holy Of Holies, so what's the comparison??

The Alter of Slabodka - From here we learn that your home can be transformed into the Holy Of Holies.

WOW!!
