The planet Jupiter represents spiritual and religious aspiration; zeal, optimism, and enthusiasm; grandiosity, largesse or “bigness”; good fortune; broad intellectual understanding; travel; the perspective of new and different cultures.  Negatively: over-exuberance, arrogance; over-indulgence and excess (similar to Venus); the neglect of important details (and therefore subsequent failure and loss); errors in judgment; and over-confidence. 

Called Guru in Vedic Astrology; transits and progression to and from Jupiter indicate times of great energy and enthusiasm, seeming to PROMISE (instead of guaranteeing) good times.  Usually there is a great abundance of ideas and grandiosity of discussions, the follow-up on which is another story. 

Many times under a Jupiter influence people will spend a lot of money. 

Under Jupiter transits usually consultations with spiritual or religious advisors go very well, the council from on high seems to really flow.  Taking part in ceremonies and rituals during these times are particularly efficacious. 

Jupiter has an actual blessing and protective influence. 

If a person has a great ability to bring things to fruition, Jupiter influences can be extremely beneficial. 

Rulership in SAGITTARIUS and PISCES.  Exaltation in CANCER.
