If Jupiter is in the second house the native will be rich and intelligent. What he foretells will come true. In his 16th year he will enjoy financial gains and agricultural prosperity. He will also be very powerful. If Jupiter is in his own sign (Sagittarius or Pisces) or in his sign of exaltation, the native will be very prosperous and wealthy.
If Jupiter is associates with a malefic there will be obstacles in educational pursuits and the native will be a thief, liar and will have vulgar speech. If Jupiter is in his sign of debilitation and associated with a malefic, the native will be a drunkard and immoral. He will be a destroyer of his family and will have relations with other people's wives. He will also be childless.
Jupiter is supposed to be the planet of good luck and Saturn the planet of bad luck. So why are there so many poor people with Jupiter here and so many rich ones with Saturn in the second house? Remember, Jupiter is where we feel lucky and optimistic, and Saturn where we feel fearful and insecure. The Saturn folks are so afraid of poverty, they work like crazy to have enough. Even when they get it, they STILL feel poor. Enough is never enough for them. Those with Jupiter in the second house, however, tend to feel "lucky". Why not? Whenever they need money, it seems to fall in their laps, so why kill yourself working?
