Yoke of Heaven reveals the mitzvos' inner taste
ol malchus Shomayim · penimiyus · reward · gashmiyus · da'as
במד' חשבתי דרכי כו'.
In the Midrash: "I considered my ways [and turned my feet to Your testimonies]" (Tehillim 119:59).
The Sefas Emes opens with the verse in which David says he reckoned and reflected upon his ways before acting — the Midrash connects this to the avodah of "Bechukosai."
פי' ע"י שחושב אדם קודם כל מעשה להיות לשמים ומביא הדעת לתוך המעשה שעושה הכל בדעת וכן בכל יום ויום כשמקבל עליו עמ"ש בבוקר זה הרצון מיישר כל מעשיו לטוב.
The meaning is: through a person thinking, before each deed, that it should be for the sake of Heaven, and bringing da'as into the act — so that he does everything with awareness — and likewise each and every day, when he accepts upon himself the yoke of Heaven (ol malchus Shomayim) in the morning, this resolve straightens all his deeds toward the good.
Before doing anything, a person should pause and direct the act lesheim Shomayim, infusing it with conscious da'as. And the daily acceptance of ol malchus Shomayim each morning (in Shema) plants a resolve that then aligns and straightens all the day's actions toward the good.
וז"ש בחקותי תלכו להיות עול מלכותו ית' על האדם שלא יוכל לעשות מעשה קטנה וגדולה קודם ההסתכלות אם הוא כרצונו ית'.
And this is the meaning of "If you walk in My statutes (bechukosai teileichu)" — that the yoke of His kingship be upon a person such that he cannot do any deed, small or great, before first considering whether it accords with His will.
"Walking in My statutes" means living under the constant ol of Hashem's kingship — so internalized that one cannot perform even a minor act without first checking whether it is in keeping with ratzon Hashem.
וקודם העבודה נראה הכל כמו חוקה וע"י קבלת העול זוכה להבין ולהרגיש טעם המצות.
And before the avodah, everything appears like a chok (a decree without evident reason); but through accepting the yoke, one merits to understand and to feel the taste (ta'am) of the mitzvos.
At the outset, before a person has labored in avodah, the mitzvos all seem like inexplicable decrees. But by first accepting the yoke without demanding reasons, one is then granted to grasp and even feel the inner flavor and meaning of the mitzvos.
וזה עצמו השכר כמ"ש שכר מצוה מצוה שמתקרב אל פנימיות המצוה.
And this itself is the reward, as it is said, "the reward of a mitzvah is a mitzvah" — that one draws near to the penimiyus (inner essence) of the mitzvah.
The reward is not external; it is the deepening itself. "The reward of a mitzvah is a mitzvah" means that performing a mitzvah brings one closer to its inner core — and that closeness is the very prize.
וכן מה שלא נזכר בתורה שכר עוה"ב כי הוא פשוט ומובן מעצמו.
And similarly, the reason the Torah does not explicitly mention the reward of the World to Come is that it is simple and self-understood.
This explains why Olam Haba's reward is not spelled out in the Torah: that the soul receives spiritual reward in the next world is obvious and needs no statement — it follows naturally from drawing close to the penimiyus of the mitzvos.
אבל זה ברכה יתירה להיות נמשך כל ברכת עוה"ז ע"פ התורה וחקותי'.
But this [the blessings in the parshah] is an extra blessing — that all the blessing of this world be drawn down in accordance with the Torah and its statutes.
The blessings promised in Bechukosai are something added: that even the material bounty of this world should flow specifically through, and in harmony with, the Torah and its mitzvos.
וז"ש גשמיכם בעתם כמ"ש בזוה"ק ע"פ לכל זמן ועת כו'.
And this is the meaning of "your rains in their season (gishmeichem be'itam)," as the Zohar HaKadosh explains on the verse "to everything there is a time and a season."
"Rains in their proper time" hints, per the Zohar, that the physical (gashmiyus, alluded to in "gishmeichem") will be drawn down at its fitting "time" — channeled in proper alignment with its spiritual root.
והיינו שיהי' גם הגשמיות נמשך אחר השורש.
That is, that even the physicality (gashmiyus) should be drawn after its root.
The promised blessing is that even material existence should follow after and stay connected to its spiritual source, rather than becoming detached and coarse.
והוא כמו שאחז"ל יפה שעה א' בתומע"ט בעוה"ז כו' א"כ זה הבטחה יתירה מעוה"ב:
And this is like what Chazal said, "Better one hour of teshuvah and good deeds in this world [than all the life of the World to Come]" — if so, this [blessing of this world] is an even greater assurance than the World to Come.
Since Chazal taught that a single hour of teshuvah and mitzvos in this world surpasses all of Olam Haba, the blessing that even this-worldly gashmiyus be drawn after its spiritual root is, in a sense, an even loftier guarantee than the reward of the next world.
Summary: "Walking in My statutes" means accepting the yoke of Hashem's kingship so completely that one weighs every act against His will before doing it, and infuses each deed with conscious da'as. Though mitzvos first appear as reason-less decrees, this acceptance earns one to feel their inner taste — for "the reward of a mitzvah is a mitzvah," drawing near to its penimiyus. Olam Haba is left unstated because it is self-evident; the added blessing of the parshah is that even this world's gashmiyus be drawn after its spiritual root — a guarantee Chazal deem, in its way, even greater than the World to Come.
