Pluto represents the unconscious urge to transform repressed ego-desires into group-desires in order to live out your role in society’s evolution.
Pluto rules the Scorpio and the Eighth House of sexuality (the act itself, as opposed to the energetic desire which is associated with Mars), obsessive desires, transformation, power, and the ingredients of great wealth (investments, banking, loans, debt, mortgages). Pluto has dominion over drastic changes that bring true upheavals.
Since Pluto is the slowest-moving planet (18 years in one zodiac sign), an entire generation will share the same Pluto sign, giving it historical importance. Drastic and permanent changes in civilization as a whole can be linked to Pluto’s movement through the signs.
On a personal level, the House that Pluto occupies in your chart will show how Plutonian energy is manifested in your life. Pluto will transform those things in your life that require regeneration, whether you desire it or not. You may experience dramatic crises or have to endure terrible suffering where Pluto is involved in your chart, but for the purpose of healing.
Pluto tears down only to transform and regenerate what has been destroyed. Pluto is associated with recklessness, mental obsession and compulsion, emotional resistance, and overall transcendence. Pluto is associated with the Underworld, the Occult, unsolved mysteries, secrets, and taboos.
