I was curious if any part of our liturgy includes a prayer for unity among all Jews? I recently heard a prayer for unity among all Xians read at a friends wedding, and was like wow we really outta pray for that, but I can’t recall anything like that in our tefillahs? Sinas chinam seems to come easily to us as a people. There are too many subgroups and sub-subgroups of Jews and division always causes tension.
To answer the original poster’s question, keep studying my friend.
“Avot d’Rabbi Natan: “If you have a sapling in your hand and people tell you that the Moshiach has come, plant the sapling and then go and greet him.””
