There is a Chabad Chasidic saying "when two get together to talk of their spiritual failings, it is two Godly souls vs. one animal soul." The reasoning is, the Godly souls are selfless and are more than happy to unite and help each other in the spiritual failing at hand. However, the animal soul is innately selfish and thus each animal soul will not join forces. Thus, at a farbrengen, when Chassidim get together to inspire one another, they have the help of each other's Godly souls, greatly out-numbering the animal souls.
