The Rebbe notes that the Alter Rebbe here offers a remarkably novel thought — that every Jew receives vitality in this world from all 613 mitzvot, even though the commandments given to Kohanim do not apply to commoners, many commandments cannot be performed simultaneously, and the like.
Possibly, continues the Rebbe, this may be understood in light of the Alter Rebbe’s explanation in Kuntreis Acharon, in the essay that begins, “To Understand the Details of the Laws...” (p. 159b.) [There the Alter Rebbe writes that even the laws that perhaps never have practical application derive from Supernal Wisdom.]
