The Torah Portion of Lech Lecha
Rabbi Shneur Zalman, the first Chabad Rebbe, said, "One must live with the time." His brother, R. Yehuda Leib, explained this to mean that one must live with the Torah portion of the week. One should not only learn the weekly portion every day, but live with it. A really joyous week is that of Lech Lecha. We live every day of the week with Abraham, the first to dedicate his very life to spreading G-dliness in the world. And Abraham bequeathed his self- sacrifice as an inheritance to all Jews. (Hayom Yom)
Go from your land (Gen. 12:1)
Ever since G-d told our father Abraham, "Go from your land etc," and subsequently "Avram kept travelling southward," we have the beginning of the mystery of birurim - elevating the sparks of holiness. By decree of Divine Providence man goes about his travels to the place where the "sparks" that he must purify await their redemption. The righteous tzadikim, who have vision, see where their birurim await them and go there deliberately. As for ordinary folk, The Cause of all Causes and the Prime Mover brings about various reasons and circumstances that bring these people to that place where lies their obligation to elevate the sparks. (Reb Shalom Dov Ber of Lubavitch)
Lech Lecha - Go from your land and your birthplace and your father's house... (Gen. 12:1).
The literal translation of the words "Lech Lecha" is "Go to yourself." Going has the connotation in Torah of moving towards one's ultimate purpose - service towards one's Creator. And this is strongly hinted at by the phrase, "Go to yourself," meaning, towards your soul's essence and your ultimate purpose, that for which you were created. (Alshich as quoted by the Lubavitcher Rebbe)
