“The portion of Beha’lotcha begins with a description of Aaron being commanded by God to light the menorah… Rashi comments that it was to be lit ‘until the flame rises up on its own [power]’… The simple meaning is that Aaron is obligated to not only light the lights but to make sure they will stay lit on their own.
Spiritually, this means that a superficial love of God from obligation or a sense of duty will not do, as that is something that is imposed from without.
Rather, true love of God must be self-generated and approached in a manner that assures that it will be an intimate and passionate love that will stay lit through all the ups and downs of life.”
