Yes, that principle is called neecha bhanga in Indian astrology. If an exalted planet or a domiciled planet is in the same sign/house as a debilitated planet, it cancels the debility. There's a number of other rules for debility cancellation.
It is said that you get the debilitated effects first then the cancellation effect comes in later. Albert Einstein is often given as an example.
Sidereally, your Jupiter is in Pisces/9th along with Mercury, Venus is in Aquarius. It's a very strong Jupiter.
I've long hoped to find more info. on finding solutions in the chart to help Mercury (Moon and Mars also). Thank you!
Are there any other rules on these kinds of cancellation that you could tell us about, or if you have on another thread? If they are too complex for here I understand.
When you say that the cancellation comes later, you mean in life? Yes I noticed Albert was also such a native and another member here Frank has done some studies on Pisces Mercury.
