Birkat Asher yatsar

Asher yatzar (Hebrew: בִּרְכַּת אֲשֶׁר יָצַר "Who has formed man") is a blessing in Judaism. It is recited after one engages in an act of excretion or urination, but is also included in many Jewish prayer books as a part of daily prayer prior to birkot hashachar. The purpose of this blessing is to thank God for good health. It expresses thanks for having the ability to excrete, for without it existence would be impossible. 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).
