During the 1980s there was a mash up of planets in Capricorn: Uranus, Neptune and Saturn. People born around that time will be in their early twenties now and you can bet they'll be feeling this Pluto transit through Capricorn.
Pluto transforms whatever it touches and it's not subtle. It reaches into the guts of the matter and tears out what is unnecessary. This is why Pluto transits often feature a figurative "death": there has to be an ending before there can be a beginning. It can be relentless, intense, and nothing is the same after it passes. You can imagine that when Pluto hits one of the outer planets (which represent life events) that the changes are huge. Three outer planets in one shot is exceptional.
Pluto (transformation) hitting Uranus (liberation) is the collision of two types of change. Pluto hitting Neptune is a transformation of ideals or creative evolution. Pluto hitting Saturn is a breakdown of existing structures. How this transit will effect each person depends on the set up of their chart. Do they have Capricorn in the 7th House? Relationships will be transformed. Capricorn in the 4th House? Home and family life will be re-constructed. This is literally the opportunity of a lifetime as the slate is scrubbed clean and the map re-drawn.
Do you or anyone you know have these planets in Capricorn?
