Musar su Esodo 4:16

Rabbi Shimon ben Yochai was sitting engaged in Torah study when an old man (i.e., the prophet Eliyahu) stood behind the wall and called to him: “Rabbi! Rabbi! Holy light! Arise and kindle the lamp. That is, the mitzvah lamp of the holy Shechinah (i.e., draw down an outpouring of illumination to the Shechinah, which is called the “mitzvah lamp”). For concerning it was it written, ‘Let a continual fire burn upon the altar, let it not be extinguished’ (Vayikra 6:6). And it is also written, ‘To kindle a continual lamp’ (Shemos 27:20). The Shechinah is certainly called the “lamp of Hashem.” It is the source of Adam HaRishon’s light, that is, his soul. Arise and kindle it!” So Rabbi Shimon ben Yochai stood on his feet (out of deference to the Shechinah) and then sat for a moment and said, “Master of All the Worlds, You are the ruler over kings and the revealer of secrets. Let it be Your will to arrange the words in my mouth in fulfillment of the verse, “And I will be with your mouth” (Shemos 4:12), so that I will not come before You in shame (after my death).”
