All levels of the soul… Particularly after having completed the first cycle of 150 years, this cycle is reflected in the opening verse of the coming week’s parshah – the Rebbe Rashab’s birthday parshah… Vayechi Sarah: “Sarah’s lifespan was 100 years and 20 years and 7 years.” The number 150 includes every aspect of divine service [performed] with all of the soul’s faculties – both the makifim [all-embracing, “surrounding” levels] of will and pleasure, along with the pnimiyim [measured, limited faculties, “internal” to the body] of intellect and emotion. As explained in Chassidus, they are alluded to in the words [of the verse], “100 years” [makifim], “20 years” [mochin – intellect], and “7 years” [midos – emotions].
At present, we are completing the first year of the second 150-year cycle since the Rebbe Rashab’s birth; all of the above-mentioned details are now elevated in a redoubled manner.
