My father z’l used to say that 99% of what passes for astrology today is absolute fabrication. The 1% that might have some meaning falls in two categories. The first is that 99% of that 1% that is in the same category as a baal ov or a baal yedoni – forbidden mideoraisa even though they have some power, according to Tanach.
The other 1% of 1% can only be interpreted through the prism of kaboloh taught by a pure and knowledgeable mekubal. There is reference to the mazalim in our davening, fyi.
