Farbrengen
A Farbrengen (, from the Yiddish פארברענגען, meaning "joyous gathering"; German verbringen "to spend [time/solidarity/festivity together]") is a Hasidic gathering. This term is only used by Chabad-Lubavitch Hasidim, as other Hasidim have a Tish or a botteh. It may consist of explanations of general Torah subjects, with an emphasis on Hasidic philosophy, relating of Hasidic stories, and lively Hasidic melodies, with refreshments being served. It is regarded as a time of great holiness. Farbrengens are public events open to non-Hasidim as well.
