Re: 5 or 6+ planets in the same sign?
Freedomlover, I think that temporarily, indeed, the concentration on that lifecompartment (house) will be stronger than usual. Depending on how long the progressed planets are situated in that house. They will also of course, conjunct the planets already there by birth position and this could give an extra, maybe mixed (with the progr. planets energy) expression to the natal planet. Maybe in the sense that, during a couple of years, the progr. planet "agrees" or will be more in tune with the expression of the natal planet and it's house.
