Where exactly does it say that? What am I missing here?
All signs are created equal, but not all signs give the Moon the same amount of comfort or power. We're reminded of this in Bonatti's 146 Considerations and most famously in Lilly's Christian Astrology; the Moon is much less impedited if she is found to be void in the signs of Taurus, Cancer, Sagittarius, and Pisces. The reason why is never made explicit, but likely has to do with these four signs being the dignities of benefic planets.
Is the Moon in a water sign considered weak in a Horary Chart?This doesn't say the moon is void in pisces.
It says that when the moon is void, and it occurs in one of the signs noted (taurus, cancer, sagittarius, pisces), the moon is less impedited, less blocked.
The moon can be void in any sign even at an early degree, if it doesn't make any further aspect with a planet before it leaves the sign it is in. This can happen in any sign. It generally means that whatever the matter is, it will not move forward, precisely because the moon does not connect.
So Moon is considered weak while in Scorpio? Ok thanks.The moon is domiciled in Cancer, which is very strong. The moon falls in Scorpio, where it is weakened. Pisces would be neutral, so look at what else is going on with a Pisces moon.
Are you familiar with the table of essential digniities?
