Maamarim of the Sixth Lubavitch Rebbe. Volume 2

Maamar (literally "speech", "saying") is a traditional form of transmitting Hasidic teaching among the Lubavitch Rebbes. Usually, the Rebbe delivered maamarim in spoken form (hence the name - maamar) during Hasidic gatherings, typically on Saturdays, holidays, and special dates.

Later, maamarim were published in written form.
