In Vedic astrology, Brahaspati is the natural karaka of four very important houses.
Jupiter is the natural karaka of 2nd house (house of wealth, speaking), 5th house (education, skill and kids), 9th house (Luck and religion) and 11th house (House of achievements).
Astrologically it is called Lord of power, Lord of wisdom, Lord of sacred talking, Guru of Gods, God of Gods, etc.
Jupiter in House No. 1 will make you a king or a hermit. You have a good learning, long life and a good fortune. Ketu, Moon and Mercury will become favourable.

You’ll have a good time in your old age if Moon is in House No. 5, and if Mercury is in House No. 5, then you will become a king.
