The lesson of Uranus is how to cultivate and maintain personal uniqueness within group identity. The last time Uranus transited Taurus, we saw a massive failure to learn this lesson unfold in Nazi Germany, where a toxic brand of Fixed Earth-based group identity took root ("Blood and Soil"). Let's hope we do better this time around. All of the current permutations of "Blood and Soil"-based hyper-nationalism which were activated during Uranus in Mars-ruled, combative Aries must now be mercilessly stamped out before they take root in Fixed Earth Taurus.
On a personal level, the planet Uranus in your natal chart indicates where your own personal need for individuation and uniqueness is located. If the planet Uranus is conjunct (with 3-5 degrees) your natal Sun or Moon, or any of your other natal planets or cardinal cusps, it plays an enhanced role in pointing to where and how and why your uniqueness must be acknowledged and honored. Failure to be true to your own individuality can and does lead to frustration and unhealthy behaviors.
Here's the schedule:Uranus enters Taurus: 15th May 2018. We're off and running. Then Uranus retrotgrades back into Aries on 6th November 2018, re-entering Taurus for the long haul on 6th March 2019, until it enters Gemini on 7th July 2025. Uranus then retrogrades into Taurus again from 8th November 2025 until it re-enters Gemini on 26th April 2026.
