"I have Pluto in transit which joins or trine Sun in the birth chart. What does it mean ?" What can it mean to have good aspects Pluto form as a conjunction, sextile or trine with our natal Sun ? What a way to give a favorable passage of Pluto, the planet Sun in our birth chart ? What does it mean to have the planet Pluto conjunct or sextile natal Sun ? The transit of Pluto conjunct, sextile or trine to natal Sun which carries positive connotations for us ? Which are meaning, significance, sense of the planet Pluto in transit in conjunction, sextile or trine at the birth Sun ? I have a good look at this planet and then jointly or forming a sextile or trine the planet Sun can bring important significance not only on a personal level. Let's say, however, that we do not take into consideration the position of Sun in the 12 astrological houses and then Pluto transiting Sun 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 : this influence, although very rare, can bring incredible energy intimate but that should be used in the most fair and appropriate and not unhealthy and sadistic. If you are in politics you could really take important positions. But generally you have sufficient forces and magnetism to make big shots in the profession. You could devote to the study of astrology, psychiatry, psychology, the occult sciences in general. You can really grow and mature very inwardly.
