Scorpio is about metamorphosis

Scorpio is the only sign that has three animal totems. First, there is the well-known Scorpion with its active tail. Second, as the Scorpio learns to master its passion and hold its instincts at bay, it changes into the Eagle. The Eagle has more perspective, for it flies high above the surface of circumstances, swooping down with its power only to kill prey for food. In its third form, the Scorpion becomes the always-peaceful dove. The real meaning of Scorpio is thus shown. Scorpio is about metamorphosis. Scorpios transform the painful poisons of possessive passion into a higher consciousness based on universal love.

Your motto might be "What is hidden is more interesting than what is obvious." You are the detectives of the zodiac. But you can also be secretive yourself, for you learn early on that when you express everything, others may be scared by the power of your feelings. You have the magic to light up the dark, but sometimes you would benefit by looking at the positive side of things rather than going into the darkness at all.

The water element of Scorpio is fixed and frozen, but it is a mistake to think that ice doesn't flow. It does flow -- and with great power. Think of a glacier, moving so very slowly, yet with enough power to flatten a forest or even a mountain.

As the key planet for Scorpio, Pluto is intense and powerful, representing those things that we don't or can't understand. And it is from these hidden Plutonic spaces that magical transformations arise.
