Why and how did Moshe Rabbeinu merit [his level]?

Where is the place in the world where one receives all the mochin?

Holy words of The Rav, Rabbi Eliezer Berland shlit"a:

The Megaleh Amukos explains on page 112 that Moshe is 10 times Ma"H (Ma"H is the Name of self-nullification and humility).

Moshe with two hei’s: M’ (mem) - Sh’ (shin) - H’ (the hei). Mem (מ-ם) is 80, shin (ש-י-ן) is 360; together (80+360) that is exactly 440. And with the two hei’s, which are 10, in total together it is 450.

450 is 10 times Ma"H. That is what the Megaleh Amukos says—that Moshe was 10 times Ma"H.

Moshe merited to be 10 times Ma"H because when people insulted him—when they wanted to stone him, four times they wanted to stone him; they were only looking to stone Moshe—Moshe accepted everything with love. He did not complain. He did not accuse them. (He judged them favorably.) He said: They are the most righteous, the most holy.

Because Moshe is 10 times Ma"H, he merited to truly be Ma"H.

In Eretz Yisrael there are all the mochin—gadlus d’gadlus. Here in Eretz Yisrael one receives all the mochin. A person is not permitted to live outside of Jerusalem.

In Jerusalem there are all the mochin: “Blessed is Hashem from Zion, Who dwells in Jerusalem—Hallelu Yah” (Tehillim 135:21). Hashem dwells only in Jerusalem.

For this is what the Rambam brings: “Who dwells in Jerusalem—Hallelu Yah”—Hashem is found only in Jerusalem. Someone who was born elsewhere—he was born there, but someone who was not born [in another place] is forbidden to leave Jerusalem. Even if he has no food, even if he lives in a basement, even if he lives underground—it doesn’t matter: we do not leave Jerusalem, “Who dwells in Jerusalem—Hallelu Yah.”

Now they are firing missiles at the whole country except Jerusalem. Jerusalem is exactly in the middle between Gaza and the Lebanese border; therefore, when they shoot from Gaza toward Jerusalem, it only reaches as far as Beit Shemesh.
