There are two ways to awaken someone: either with a loud sound or by turning on the lights. On Rosh Hashanah, we are awakened by the loud call of the shofar. On Chanukah, we are awakened by the bright lights of emunah that shine from the Chanukah menorah. We awaken to the light of emunah. ~ R’Shlomo Eiger of Lublin hy’d zt’l as cited by R’ Biderman
