Astrologically Jupiter is associated with the principles of growth, expansion, prosperity and good fortune; and a person's inner sense of justice and morality and their ideals and higher goals. Jupiter governs long distance and foreign travel, higher education, religion and the law. It is also associated with the urge for freedom and exploration, humanitarian and protecting roles, and with gambling and merrymaking or 'joviality'. The first-century poet Manilius described Jupiter as temperate and benign, and the greater benefic. It was regarded as warm and moist in nature, and therefore favorable to life.
In medicine Jupiter is associated with the liver, pituitary gland and the disposition of fats. It also governs the blood. Improving your relationship with the energies of Jupiter in your body could potentially improve the function of your liver, pituitary, and blood circulation. Also, your long distance, foreign travel, higher education, religious energies, and ability to interact with the law in a positive way are influenced by positive Jupiter energy.
