The Hadran is traditionally recited at the completion of a seder of Mishnah or a tractate of the Talmud. Gary Weisserman adapted it for graduates when he was the Head of School at Bernard Zell Anshe Emet Day School in Chicago (published with permission):
Our God and God of our ancestors, Who graciously endows us with intelligence, wisdom, perspective, understanding, and the infinite capacity for empathy and kindness: May our students, and the students of our students, Be found worthy of merit, and return safely to their study. We ask for them peace and lovingkindness; May they be blessed with all they need, With their own intelligence, with their own understanding, With the wisdom they need for a lifetime of learning, And with the strength of heart and soul to apply that learning to mending an imperfect world. May it be your will that they return soon to their learning, May they be kept safe, and secure in their identity, their faith, and the embrace of their people and culture May the threshold to their new places of learning be no stumbling block to young or straying feet And may they thrive in leading us, we your people Israel, for now and in the future. And let us say, amen.
