"I have Pluto in transit opposing or squaring Saturn in the birth chart. What is involved ?" What can it mean to have bad form Pluto aspects such as quadrature and opposition with our natal Saturn ? What a way to give an unfavorable passage of Pluto on the planet Saturn in our birth chart ? What does it mean to have the planet Pluto square or opposed natal Saturn ? The transit of Pluto quadrature and opposition to natal Saturn which carries positive connotations for us ? Which are meaning, significance, sense of the planet Pluto in transit in square or opposition at the birth Saturn ? Having this planet in bad aspect and then square (90 degrees) or that form an opposition (180 degrees) with the planet Saturn can bring important significance not only on a personal level. Let's say, however, that not take into consideration the position of Saturn in the 12 astrological houses and then Pluto transiting Saturn which is in I, II, III, IV, V, VI, VII, VIII, IX, X, XI, XII house. This is because Pluto 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 : is certainly one of the best transits to suffer even say clearly that it is one of the worst. You could really suffer a try very hard to deal with and overcome in a short time, especially if you get older. Try to better manage what you want to do with what you actually do.
