Holy speech draws Divine inspiration

שמחת בית השואבה שמשם שואבין רוח הקודש.

The Simchas Beis Hashoeivah (the Joy of the Water-Drawing) is the place from which one draws ruach hakodesh (Divine inspiration).

The Sefas Emes teaches that this celebration was not merely about water; its inner content was the drawing-down of holy spirit upon Bnei Yisrael.

דכ' ויפח כו' ויהי האדם לנפש חי' ותרגומו לרוח ממללא.

As it is written, "And He breathed... and man became a living soul" (Bereishis 2:7), which the Targum renders as "a speaking spirit."

The very life Hashem breathed into man is the power of speech — the soul expresses itself through holy words.

לכן אחר ר"ה ויוהכ"פ שניתן החיים לאדם ונתחדש רוח חיים בקרבו זוכה לרוה"ק.

Therefore, after Rosh Hashanah and Yom Kippur, when life is granted anew to man and a fresh ruach chaim (spirit of life) is renewed within him, he merits ruach hakodesh.

The Yamim Noraim recharge a person's inner vitality, and this renewed soul-life becomes a vessel for Divine inspiration on Sukkos.

וכמ"ש בגמ' תינוק מתחיל לדבר אביו מלמדו תורה.

As the Gemara says: when a child begins to speak, his father teaches him Torah.

The awakening of speech in a person is precisely the moment to channel it toward Torah — speech and Torah are bound together.

לכן בימים אלו נפתחים שערי דיעה בלבות בנ"י.

Therefore, in these days the gates of da'as (understanding) are opened in the hearts of Bnei Yisrael.

This season is uniquely fit to receive deeper knowledge of Hashem, for the heart has been opened by teshuvah.

ולכן שמחת תורה אחר סוכות.

And this is why Simchas Torah comes after Sukkos.

Once the gates of da'as are opened, the natural culmination is rejoicing with the Torah itself.

ובנבואה יש כמה מדריגות.

Within nevuah (prophecy) there are many levels.

Prophecy is not a single state but a ladder of ascending degrees of Divine connection.

ושורש הכל הוא הדיבור שיכול אדם להוציא דברי תורה כראוי.

And the root of them all is speech — that a person is able to bring forth words of Torah as is fitting.

The foundation of every level of inspiration is the capacity to give proper voice to Torah.

כמ"ש ז"ל שם נביא מלשון ניב שפתים.

As Chazal said, the word "navi" (prophet) derives from "niv sefasayim" (the expression of the lips).

The essence of prophecy is rooted in articulate, holy speech — the prophet is one whose lips give voice to the Divine.

לכן גם מי שאינו בא למדריגת נביא.

Therefore, even one who does not reach the level of a navi —

Even a person who is far from actual prophecy can still tap into its root.

אעפ"כ בהתעוררות רוח חיים ויכול להוציא דברי תורה מפיו נקרא רוה"ק וזהו עיקר השמחה כשבא האדם אל שלימות רוח שבקרבו כמ"ש שמחה לאיש במענה פיו:

Nevertheless, through the awakening of the spirit of life, when he is able to bring forth words of Torah from his mouth, this is called ruach hakodesh; and this is the essence of the joy — when a person arrives at the wholeness of the spirit within him, as it is written, "A man has joy in the answer of his mouth" (Mishlei 15:23).

True simchah is reached when the inner soul finds full expression in words of Torah — that is the real "water-drawing" of holy spirit available to every Jew.

Summary: The Simchas Beis Hashoeivah draws ruach hakodesh because the soul Hashem breathed into man is a "speaking spirit." After the renewal of the Yamim Noraim, the gates of da'as open and every person — even one far from prophecy — can give voice to Torah, and that holy expression of the inner soul is the deepest joy of Sukkos.
