Asher yatzar (Hebrew: בִּרְכַּת אֲשֶׁר יָצַר "Who has formed man") is a blessing in Judaism. It is recited after engaging in an act of excretion or urination,[1] but is also included in many Jewish prayer books as a part of daily prayer prior to birkot hashachar.[2]
The purpose of this blessing is to thank God for good health.[1] It expresses thanks for having the ability to excrete, for without it existence would be impossible.[3] Though recited normally by observant Jews each time excretory functions are used, it is also recited during the Shacharit service due to its spiritual significance (to Jews, humans are made in God's image, so it is an expression of awe toward God's creations).[3]
The obligation to recite a blessing upon leaving the bathroom could be traced to the following passage in Berachot (60b):[4]
One who enters a latrine should say [to the ministering angels who accompany him], "Be honored, honored and holy ones who serve the Most High! Give glory to the God of Israel; leave me while I enter and do my will [i.e., relieve myself], then I will come to you."
Abaye objects to saying the above, and suggests one should recite something else prior to relieving oneself as well as recite a blessing similar to Asher Yatzar upon exiting the latrine.
Abaye said: A person should not speak like this, for they might leave him and go; rather, he should say, "Guard me, guard me, help me, help me, support me, support me, wait for me, wait for me until I enter and come out, for this is the way of human beings." When he comes out, he says, "Blessed... who has formed man with wisdom and created within him many openings and hollow spaces. It is obvious and known before Your Seat of Honor, that if even one of them would be opened, or one of them would be sealed, it would be impossible [to survive and] to stand before You."
A dispute over what the conclusion (chasima) of the blessing should be is recorded:
How is it to be concluded? Rav said, "who heals the sick." Shmuel said: Does Abba [Rav] regard the whole world as sick? Rather, [the conclusion of the benediction should be] "who heals all flesh." Rav Sheshet said "who acts wondrously." Rav Papa said: Let us therefore say both: "who heals all flesh and acts wondrously."
The Halakha follows Rav Papa.
After completing urination or defecation and upon leaving the bathroom, the person washes their hands. According to Jewish etiquette, this should be done outside the bathroom, but if there is no source of water available outside the bathroom, it is permissible to wash one's hands inside the bathroom, then dry them outside; some are lenient in modern bathrooms to wash in the bathroom, as our bathrooms are much more clean than the outhouses of the olden days. No al netilat yadayim blessing is recited for the handwashing.[2]
Following the washing and drying of one's hands, the asher yatzar blessing is recited.
There is no consensus as to whether or not (or how often) a person with medical issues should recite Asher Yatzar:[5]
