The transit of Neptune quadrature and opposition to natal Jupiter which carries positive connotations for us? Which are meaning, significance, sense of the planet Neptune in transit in square or opposition at the birth Jupiter? Having this planet in bad aspect and then square (90 degrees) or that form an opposition (180 degrees) with the planet Jupiter can bring important significance not only on a personal level. Let's say, however, that not take into consideration the position of Jupiter in the 12 astrological houses and then Neptune transiting Jupiter which is in I, II, III, IV, V, VI, VII, VIII, IX, X, XI, XII house. This is because Neptune is a generational planet, and therefore its influence rather than on the individual and therefore on its areas of life takes place and acts on an entire generation, an entire community.
Meaning: Be careful not to commit crimes that could create you any serious problems with the law. In the majority of cases with aspects of quadrature and opposition can attend a defect that arises or becomes worse as drinking and smoking, or you can go overboard in 'drug use. Also be careful not to gain weight and to keep an eye on your water retention especially if you are female.
