THE TOOL THAT BRINGS MOSHIACH
The reward of a mitzvah is the mitzvah itself. (Avos 4:2)
Moshiach is the reward for the study of Chassidus, and Chassidus is the tool that brings Moshiach. In reality, Moshiach and Chassidus are two sides of one coin. The more we learn Chassidus, the more we internalize and begin to experience Moshiach.
