Rabbi Shmaryahu Gurary ("Rashag") was born in 1898; his father, a wealthy businessman and erudite scholar, was a leading chassid of the fifth Lubavitcher Rebbe, Rabbi Sholom DovBer Schneersohn (1860-1920). In 1921, Rabbi Shmaryahu married Chanah Schneersohn (1899-1991), the oldest daughter of the 6th Lubavitcher Rebbe, Rabbi Yosef Yitzchak Schneersohn (1880-1950). When Rabbi Yosef Yitzchak passed away in 1950, there were those who saw Rabbi Shmaryahu -- an accomplished Chassidic scholar and elder of the Rebbe's two surviving sons-in-law -- as the natural candidate to head the movement; but when the younger son-in-law, Rabbi Menachem Mendel, was chosen as rebbe, Rabbi Shmaryahu became his devoted chassid. Rabbi Shmaryahu served as the executive director of Tomchei Temimim, the world-wide Lubavitch yeshiva system -- a task entrusted to him by his father-in-law -- until his passing on the 6th of Adar I in 1989.
People have the wrong idea about restrictions: They imagine that if you restrict what you eat and what you do not, when you work and when you meditate and pray, what you wear, where you go—all these restrictions will suffocate any sense of inspiration.
The truth is, without any restrictions your inspiration will quickly dissipate. Focus your light like a laser into an intense, powerful beam, and it will last.
