Da'at Tevunot - The Knowing Heart: Section 6, Chapter 9
(¶ 172 - 174 [beg.])
1. We’d now need to explain something else essential to God’s interactions
with us that’s beyond the reward-and-punishment paradigm and Mazal .
For while both of those are tailored to one’s own makeup and ultimate needs,
there are other, this-worldly and universal forces that follow a course of
their own. They’re rooted in the needs of the moment at hand, and they have
to do with the aforementioned astrological influences.
2. We’re taught that the stars and constellations act as particular and
special conduits of G-d’s interactions with the world, and that they
function in that capacity in relation to each other and to everything here
below. But it’s important to know a couple of things about them for our
First, that each star and constellation influences a particular person,
place, or thing, and that each of the latter is influenced by one star or
constellation alone at any one point. Yet, each star and constellation also
has its own specific moment, hour, day, or era to “shine” (if you’ll pardon
the pun) -- a point at which it matters most especially in the grand scheme.
Understand, of course, that there’s a significant difference between the
two. For, when a particular star or constellation interacts with someone or
something specific, that’s so because there’s an intrinsic and singular
relationship between star and object, and because the heavenly body has a
particular hold over it. When a particular star or constellation has a
special task of its own, on the other hand, then it holds sway over
everything in broad strokes.
As we’ll see, all this goes to explain G-d’s interactions with us in general.
