I mean, how does one choose between the lord of the relevant house in the nativity and the planet traditionally governing the relevant effect desired? If I wanted to win the lottery and Saturn were the lord of my fifth house, when would I invoke Saturn and when would I invoke Venus? Is it just a matter of convenience? Like if Saturn had greater essential dignity, would one go that route? Can’t seem to locate guiding principles on this matter.
