Chanukah - Lighting Left
It seems to me that the right side is usually given precedence in performing mitzvot. Why is the Chanukah menorah lit on the left side of the doorway?
Many people nowadays light inside the house either on a table or in the window. But it is correct that according to the original halacha, and as still practiced by many today, the ideal location to light the Chanukah menorah is on the left side of the main, outer doorway into the house.

And even now, while the Temple is not built, the light of the Chanukah menorah illuminates our path in exile.
In a similar light, the original altar was consecrated on the 25th of Kislev, the same day on which Chanukah was later instituted. The mitzvah of making a sanctuary for
