The proper functioning of the body is highly complex and delicately balanced. It is a system that we usually take for granted. The Torah wants us to appreciate every aspect of life, even the routine. The Sages composed a blessing that celebrates and gives thanks to God for the proper, regular functioning of the digestive and waste systems of the human body. The blessing is recited after relieving oneself any time during the day, but is first recited after the blessing for washing the hands in the morning.
There is an amazing story about this blessing told by Dr. Kenneth M. Prager, of Columbia Presbyterian Medical Center in New York:
When I was an elementary school student in yeshiva - a Jewish parochial school with both religious and secular studies - my classmates and I used to find amusing a sign that was posted just outside the bathroom. It was an ancient Jewish blessing, commonly referred to as the asher yatzar benediction, that was supposed to be recited after one relieved oneself. For grade school children, there could be nothing more strange or ridiculous than to link to acts of micturition and defecation with holy words that mentioned God's name. Blessings were reserved for prayers, for holy days, or for thanking God for food or for some act of deliverance, but surely not for a bodily function that evoked smirks and giggles.
It took me several decades to realize the wisdom that lay behind this blessing that was composed by Abayei, a fourth-century Babylonian rabbi.
Abayei's blessing is contained in the Talmud, an encyclopedic work of Jewish law and lore that was written over the first five centuries of the common era. The Jewish religion is chock-full of these blessings, or brachot, as they are called in Hebrew. In fact, an entire tractate of Talmud, 128 pages in length, is devoted to brachot.
On page 120 (Brachot 60b) of the ancient text it is written: "Abayei said, when one comes out of a privy he should say: Blessed is He who has formed man in wisdom and created in him many orifices and many cavities. It is obvious and known before Your throne of glory that if one of them were to be ruptured or one of them blocked, it would be impossible for a man to survive and stand before You. Blessed are You that heals all flesh and does wonders."
An observant Jew is supposed to recite this blessing in Hebrew after each visit to the bathroom. We young yeshiva students were reminded of our obligation to recite this prayer by the signs that contained its text that were posted just outside the restroom doors.
It is one thing, however, to post these signs and it is quite another to realistically expect preadolescents to have the maturity to realize the wisdom of and need for reciting a 1600-year-old blessing related to bodily functions.
It was not until my second year of medical school that I first began to understand the appropriateness of this short prayer. Pathophysiology brought home to me the terrible consequences of even minor aberrations in the structure and function of the human body, At the very least, I began to no longer take for granted the normalcy of my trips to the bathroom. Instead, I started to realize how many things had to operate just right for these minor interruptions of my daily routine to run smoothly.
I thought of Abayei and his blessing. I recalled my days at yeshiva and remembered how silly that sign outside the bathroom had seemed. But after seeing patients whose lives revolved around their dialysis machines, and others with colostomies and urinary catheters, I realized how wise the rabbi had been.
And then it happened: I began to recite Abayei's bracha. At first I had to go back to my siddur, the Jewish prayer book, to get the text right. With repetition - and there were many opportunities for a novice to get to know this blessing well - I could recite it fluently and with sinceri
