This is an auspicious day to reflect and ask the Rebbe to intercede on High on behalf of the Lubavitch movement.
They need to select a new Rebbe. 15 years - it is way overdue.
To remain Hasidim in good standing, Lubavitch Hasidim need to name a new rebbe already.
That is the main definition of Hasidism - to be followers of a living rebbe.
