In this lecture we learn about “A Continual Fire” which is to remain on the Altar.
In his Likkutei Torah (Devarim 78d) Rabbi Schneur Zalman of Liadi explains that the altar is the heart of the Jew. And corresponding to the two altars of the Sanctuary, the outer and the inner, are the outer and inner levels of the heart, its surface personality and its essential core.
The altar on which the continual fire was to be set was the outer one. And for the Jew this means that the fire of his love for G-d must be outward, open and revealed. It is not a private possession, to be cherished subconsciously. It must show in the face he sets towards the world.
