With the approach of the German army during World War I, R. Sholom DovBer and his family left Lubavitch, located in modern-day Russia near the border of Belarus, for the city of Rostov. Lubavitch was the seat of the Chabad movement for 102 years, starting when R. DovBer, second Chabad Rebbe, settled there in 1813.

Within every love, there is fear: The fear of separation from that which you love.
A child fears separation from her parents, a lover from his beloved, the body fears separation from the soul, and the soul from its Source Above.
So what do you love? Look at your worries and you will know. If you seethe in worry over your debts and financial future, then it is the material world you love—because you believe in the material world and you see it as the source of all good.
If you sit and fret over the comments of others and the glances they throw at you, then it is social acceptance that you love, that you have made into your god.
Cleave to the Source of Life and your heart will have no room for fear of this world.
