Joining Torah's holiness to physical deeds

במד' וכי תבואו כו' ונטעתם כו' עץ חיים היא כו'.

In the Midrash: "When you shall come [into the land]… and you shall plant…" (Vayikra 19:23) — "It is a tree of life…" (Mishlei 3:18).

The Midrash connects the pasuk about planting upon entering the land with the verse describing the Torah as a "tree of life," hinting that the true "planting" is the Torah.

כי חיי עולם נטע הוא תורה שבע"פ המשכת כח. התורה במעשה.

For "eternal life He planted within us" (from the berachah on the Torah) refers to the Oral Torah — the drawing of the Torah's power into action.

The phrase "eternal life He planted within us" alludes to Torah she-be'al peh (the Oral Torah), whose function is to bring the power of Torah down into concrete deeds and physical life.

וז"ש יפה ת"ת עם ד"א שיגיעת שניהם כו'.

And this is the meaning of "Torah study is fine together with derech eretz (a worldly occupation), for the toil of the two of them [makes sin forgotten]…" (Avos 2:2).

This explains the Mishnah: combining Torah with worldly engagement, and laboring at both, is precisely the avodah of joining Torah's holiness to material life.

שזה יותר יגיעה מתורה.

For this is greater toil than Torah [study alone].

Uniting Torah with physical action demands even more effort than abstract learning, because it requires elevating the material itself.

כמ"ש בזוה"ק תרומה דקיימא בעובדא לא בא רק בטורח גדול וטהרה יתירה ע"ש.

As the Holy Zohar writes (Terumah) — that what stands in deed comes only through great exertion and extra purity (see there).

The Zohar teaches that whatever must be realized through physical action is attained only with great labor and heightened purity, since the material resists holiness.

והוא היגיעה לחבר שניהם מעשה גשמי עם הקדושה שהיא חיות הפנימיות.

And it is the toil of joining the two — the physical deed with the holiness that is the inner vitality.

The labor consists of fusing the outer physical act with the penimiyus (inner dimension) — the holy chiyus (life-force) that lies within it.

שבכ"ד יש חיות מהתורה כמ"ש באורייתא ברא קוב"ה עלמא.

For in every thing there is vitality from the Torah, as it is said: "With the Torah the Holy One, blessed be He, created the world" (Zohar, Bereishis).

Since Hashem created the world by means of the Torah, every created thing contains within it a spark of Torah's life-force, waiting to be revealed.

וכן שמעתי מאא"ז מו"ר ז"ל על שהי' קשה לישראל לכנוס לא"י שהי' עבודה רבה כנ"ל ע"ש.

And so I heard from my grandfather, my teacher and master, of blessed memory, regarding why it was difficult for Bnei Yisrael to enter Eretz Yisrael — that it required great avodah, as above (see there).

His grandfather explained that entering the Land was hard precisely because it demanded this greater avodah — the work of joining Torah's holiness to the physical life of settling and working the land.

שבמדבר הי' רק תורה ובא"י הי' יגיעת שניהם כנ"ל בחי' תורה שבע"פ:

For in the wilderness there was only Torah, but in Eretz Yisrael there was the toil of the two of them, as above — the aspect of the Oral Torah.

In the midbar (wilderness), Bnei Yisrael lived a life of pure Torah, detached from material labor. Entering Eretz Yisrael meant taking up the harder avodah of the Oral Torah: drawing Torah's holiness down into the physical work of the land.

Summary: The "planting" upon entering the land alludes to the Oral Torah, which draws the power of Torah into physical deeds. Uniting Torah's holiness with material action is a greater labor than study alone — requiring great exertion and purity — because every created thing holds a hidden spark of Torah-life that must be revealed. This is why entering Eretz Yisrael was so demanding: the wilderness was pure Torah, but the Land called for the harder avodah of joining the holy inner vitality to physical life.
