Hashem guards tzaddikim from pride

מה נורא המקום הזה.

"How awesome is this place!"

Yaakov utters these words upon awakening from his dream at the site of the future Bais Hamikdash, sensing the overwhelming kedushah of the place.

תלה אבינו יעקב התגלות הקדושה בעבור קדושת המקום.

Yaakov Avinu attributed the revelation of holiness to the kedushah of the place.

Yaakov, in his humility, credited the great revelation he experienced to the inherent sanctity of the location rather than to his own merit.

ובאמת חכמינו ז"ל הגידו כי קפץ הר המורי' ובא אליו.

And in truth, our Chachamim of blessed memory taught that Har HaMoriah leaped and came to him.

Chazal relate that the mountain of the Akeidah miraculously "jumped" from its place to meet Yaakov — showing that the holiness was actually drawn to him.

נמצא הכל אמת שהרגיש שהמקום גורם ואעפ"כ הי' הכל בזכותו.

It emerges that both are true: he sensed that the place was the cause, yet nevertheless it was all on account of his own merit.

Both perceptions are correct — the place genuinely had a role, yet the holiness came to that place only because of Yaakov's zechus; the two are not a contradiction.

והוא מפלאות הבורא ית'.

And this is one of the wonders of the Creator, may He be blessed.

This arrangement, whereby a tzaddik's own merit is hidden from him and credited instead to external causes, is a hidden wonder of Hashem's ways.

אשר הוא שומר אוהביו לבלתי יבואו במעשיהם לידי גבהות.

For He guards those who love Him, that their deeds should not lead them to haughtiness.

Hashem protects His beloved tzaddikim from the danger of gaavah (pride) by concealing from them how much their own merit accomplishes.

לכן מסבב סיבות שינהגו בהם התמימי דרך כנ"ל:

Therefore He arranges causes through which those who are wholehearted in their way are led, as explained.

Hashem orchestrates circumstances — such as making it appear that the place caused the revelation — so that the wholehearted remain in their tmimus (sincere simplicity) and never fall to pride.

Summary: When Yaakov credited the revelation to the holiness of the place rather than to himself, both were true — the holiness came to that place only through his merit, but Hashem conceals this from His beloved ones to guard them from gaavah, arranging circumstances that keep the wholehearted in humble simplicity.
