What is the Asher Yatzar (bathroom) prayer?

The Asher Yatzar (אֲשֶׁר יָצַר — "Who formed") is a short blessing recited after using the bathroom, expressing gratitude to God for the miraculous functioning of the human body. It acknowledges that the proper opening and closing of the body's orifices is essential for life, and that any malfunction would make it impossible to stand before God. It is one of the most frequently recited blessings in Jewish life.

Key Takeaways

Asher Yatzar is recited after every use of the bathroom, by men and women alike.
The blessing marvels at the complexity of the human body and recognizes that health itself is a divine gift.
Its text is sourced in the Talmud [Berakhot 60b], where it appears alongside other morning blessings.

The blessing concludes with praise of God as rofeh kol basar (הָרוֹפֵא כָל בָּשָׂר) — "Healer of all flesh."

The Text of Asher Yatzar

The full text of the blessing, as established in the Talmud [Berakhot 60b], is:

בָּרוּךְ אַתָּה יְהֹוָה אֱלֹהֵינוּ מֶלֶךְ הָעוֹלָם, אֲשֶׁר יָצַר אֶת הָאָדָם בְּחָכְמָה, וּבָרָא בוֹ נְקָבִים נְקָבִים, חֲלוּלִים חֲלוּלִים. גָּלוּי וְיָדוּעַ לִפְנֵי כִסֵּא כְבוֹדֶךָ שֶׁאִם יִפָּתֵחַ אֶחָד מֵהֶם אוֹ יִסָּתֵם אֶחָד מֵהֶם, אִי אֶפְשַׁר לְהִתְקַיֵּם וְלַעֲמוֹד לְפָנֶיךָ. בָּרוּךְ אַתָּה יְהֹוָה, רוֹפֵא כָל בָּשָׂר וּמַפְלִיא לַעֲשׂוֹת.

"Blessed are You, Lord our God, King of the universe, Who formed (yatzar) man with wisdom, and created within him many openings and many cavities. It is obvious and known before Your Throne of Glory that if one of them were to be ruptured or blocked, it would be impossible to survive and to stand before You. Blessed are You, God, Who heals all flesh and acts wondrously."

Talmudic Source

The blessing originates in [Berakhot 60b], where the Talmud records the formula to be recited upon exiting the bathroom (beit hakisei). The passage in the retrieved sources reads:

"כִּי נָפֵיק, אוֹמֵר: בָּרוּךְ..." — "When one exits, one says: Blessed..."

The Talmud there also records a related teaching about what one should say before entering the bathroom — Abaye (Amoraim, 3rd–4th century Babylonian sage) rules that one should NOT say a formula that dismisses one's guardian angels entirely (lest they leave and not return), but rather ask them to wait and guard — "שִׁמְרוּנִי שִׁמְרוּנִי" ("Guard me, guard me") — until one exits [Berakhot 60b].

Connection to "Asher Yatzar" in the Seven Wedding Blessings

Interestingly, the retrieved source from [Ketubot 8a] cites a parallel blessing recited at a wedding:

"אֲשֶׁר יָצַר אֶת הָאָדָם בְּצַלְמוֹ, בְּצֶלֶם דְּמוּת תַּבְנִיתוֹ, וְהִתְקִין לוֹ מִמֶּנּוּ בִּנְיַן עֲדֵי עַד" "Who created man in His image, in the image of the likeness of His form, and prepared for him — from himself — an eternal structure."

This is one of the Sheva Berakhot (Seven Wedding Blessings) and shares the same root as Asher Yatzar, emphasizing that yetzira (formation/creation) of the human body is always cause for blessing and wonder.

Theological Depth

The Body as a Marvel

The blessing reflects a distinctly Jewish view: the physical body is not base or shameful, but a divine masterpiece. The act of digestion and elimination — seemingly mundane — is reframed as a daily miracle. This connects to the broader Torah theme found in [Genesis 2:8], where God personally plants the Garden and places the human being there, indicating God's intimate involvement in the physical world.

Nifla'ot — Wonders in the Ordinary

The closing phrase "מַפְלִיא לַעֲשׂוֹת" ("Who acts wondrously") echoes the language of Psalms and the Hallel, reminding us that wonder (pele) is not reserved for the splitting of the sea — it is present in every heartbeat and every functioning organ.

Halachic Details

When to recite it: After every use of the bathroom, both for urination and defecation [Shulchan Aruch, Orach Chaim 7:1].
If forgotten: If one forgot and already recited another blessing, most poskim (halachic decisors) hold one need not go back, but should try to recite it in its proper time.
Hands: One should wash hands (netilat yadayim) before reciting the blessing, though there is discussion among poskim about whether this is strictly required.
Children: Children should be trained to recite it as part of their Jewish education.
