Jupiter is where we are overly indulgent, I always have used the saying with Jupiter being ‘our eyes are bigger than our stomach’ you know when we fill up our plate because we think we can eat soooo much cause it all looks so good, more than we can really fit in. Jupiter bolsters our confidence, its good for a bit, until it becomes grandiose, its an area we have trouble reining in on impulse and pleasure. Whenever Jupiter is signifies where we can have trouble stopping. Jupiter in the 3rd can talk under concrete and in the 9th keep going back to uni over and over and over again for example. Unaspected Jupiter would come on abruptly like a ‘drunk switch’ where they can’t control, there is no release valve for the gluttonous Jupiter and hence the binge or purge, all good sense goes out the window. I know someone with an unaspected Jupiter in the 8th house. He is moneybags. But he also hoards, he’s a drug addict, and puts $100 notes in the pokies, he doesn’t know when to stop.
