Mitzvos as the soul's lamp purifying the body

במדרש ה' חפץ למען צדקו כו'.

In the Midrash on "Hashem desired, for the sake of his righteousness..." (Yeshayahu 42:21).

The Sefas Emes opens with the verse the Midrash applies to Hashem's gift of Torah and mitzvos to Israel.

כמ"ש במשנה רצה הקב"ה לזכות את ישראל הרבה להם תורה ומצות דכתיב ה' חפץ כו'.

As stated in the Mishnah: "The Holy One, blessed be He, wished to grant merit to Israel, therefore He gave them abundant Torah and mitzvos, as it is written 'Hashem desired...'" (Makkos 3:16).

The well-known Mishnah teaches that the very purpose of the multitude of mitzvos is to grant Israel merit — they are a gift, not a burden.

פי' כמו שנשתלחו נשמות בנ"י ונתלבשו בגופים שפלים כדי לתקן עולמות התחתונים.

The explanation: just as the neshamos of Bnei Yisrael were sent down and clothed in lowly bodies in order to rectify the lower worlds.

The soul descends from its lofty source and is "dressed" in a physical body so that it can accomplish tikkun (rectification) in the lower, material worlds.

צדקה עשה לנו השי"ת להפיס דעתינו במה שכמו כן נתן לנו המצות שהוא התפשטות הארה מתורה אור לתוך המעשה והם מכוונים נגד רמ"ח איברים כו' לזכותנו שהמצות מסייעין לזכך הנפש כמ"ש מצות ה' ברה כו'.

Hashem did us a kindness, to set our minds at ease, in that He likewise gave us the mitzvos — which are the spreading-forth of a radiance from the "Torah of light" into action, and which correspond to the 248 limbs — in order to grant us merit, for the mitzvos assist in purifying the soul, as it is written "The mitzvah of Hashem is clear, enlightening the eyes" (Tehillim 19:9).

Knowing that the soul might feel "exiled" in a lowly body, Hashem graciously reassured us by giving mitzvos. Each mitzvah channels the light of Torah into a physical act, and the 248 positive mitzvos parallel the 248 limbs of the body — so that performing them purifies the very physical self the neshamah inhabits.

וכענין שאמרו חז"ל בלבנה שהרבה צבאותי' להפיס דעתה ע"י הכוכבים.

And this is like what Chazal said regarding the moon — that He increased its hosts to console it, by means of the stars.

Just as Hashem comforted the diminished moon by surrounding it with multitudes of stars, He consoles the descended soul by surrounding it with the "stars" of the mitzvos.

כמו כן סיוע נר מצות כי שורשן של נשמת ישראל אור תורה ממש.

So too is the assistance of the "lamp of mitzvah," for the root of the neshamah of Israel is literally the light of Torah.

The mitzvos are a "lamp" that helps the soul, since the soul's very source is the light of Torah — "for a mitzvah is a lamp and Torah is light" (Mishlei 6:23). The mitzvos reconnect the soul to its origin.

והנה כתיב אתה תאיר נרי.

Now, it is written: "For You will light my lamp" (Tehillim 18:29).

One verse describes Hashem as the One who lights the lamp of the soul — the soul is illuminated by Him.

ופ"א כתיב אתם נרי.

And once it is written: "You are My lamp..." (cf. II Shmuel 22:29).

Another verse reverses the relationship: the soul of Israel is, as it were, Hashem's own lamp.

וזה יתקיים לעתיד שיתבטלו נשמות בנ"י אליו ית' ממש.

And this will be fulfilled in the future, when the neshamos of Bnei Yisrael will be nullified to Him utterly.

The higher relationship — Israel as Hashem's lamp — will be fully realized in the future era, when the souls of Israel achieve complete bittul, merging entirely with Hashem.

ושניהם אמת שיש כמה מיני נשמות.

And both are true, for there are several types of neshamos.

Both verses hold: souls vary in their level — some are "lit by Him," while loftier ones become "His lamp" through bittul.

ובש"ק יורדין הארות מבחי' אתה נרי לכן בשבת ניתנה תורה שיש התגלות מבחי' תורה אור כנ"ל והוא מעין עוה"ב כנ"ל והוא בחי' נשמה יתירה:

And on Shabbos Kodesh, illuminations descend from the aspect of "You are My lamp"; therefore the Torah was given on Shabbos, for there is a revelation from the aspect of the "Torah of light," as above — and this is a foretaste of the World to Come, as above — and this is the aspect of the neshamah yeseirah (the additional soul).

On Shabbos, lights from that higher level ("Israel as Hashem's lamp") descend into the world. This is why the Torah was given on Shabbos, and why Shabbos is a taste of Olam Haba — the extra soul of Shabbos, the neshamah yeseirah, embodies this elevated, future-like illumination of bittul to Hashem.

Summary: The abundance of mitzvos is Hashem's kindness to the soul, which descends into a lowly body to rectify the lower worlds. Like the stars consoling the diminished moon, the mitzvos — channeling the "Torah of light" into action, paralleling the 248 limbs — purify the body and reconnect the soul to its source in Torah-light. Two verses describe the soul as both "lit by Hashem" and as "Hashem's own lamp"; the latter, the level of complete bittul, will be fully realized in the future, and is tasted now on Shabbos, when the Torah was given and the neshamah yeseirah descends.
