My son (4th grade) had a class Chanukah party, for which he was aked to prepare a devar Torah. A short vertl, a question and answer to fit in less than a minute.
My son wanted to know why we light the Chanukah menorah starting from the left candle and working your way to the right. Usually mitzvos start on the right! He was so drawn to this question, he was going to present it even though he didn’t have an answer.
Here’s what we eventually came up with (2 minutes before “showtime”):
One of the most important things in Yahadus is to constantly growing, to always try to be a greater tzadiq than one was the day before. We light the left candle first because it is the new candle. As we rule (following Beis Hillel), we light every day more than the day before because “ma’alin beqodesh velo moridin – we ascend in holiness, not refress”. We therefore start with the symbol of progress.
