Uranus opposite Sun transit is affecting the Libra sign from 2011 to 2019. This will present a year or so challenges as you feel the consequences or rapid or unexpected changes in your life. The unpredictable nature of the changes means that you are likely to be on edge a lot of the time and have to react quickly to changing circumstances.
Uranus not only represents change but also freedom and higher awareness. With the opposition, it may be that your freedom is challenged or that you are not able to express your individuality as freely as you would normally. Stability and security may be difficult to maintain under this influence, both in the material world, within your own psyche, and with relationships.
Learning to adapt to change will be a key theme during this time. Tension may build up due to unforeseen circumstances or from other people changing their behavior or attitude to you. Understanding the reasons why you are experiences this is very important. Fortunately the higher self-awareness from Uranus allows you to look at yourself from a detached point of view. To see if it is, in fact, you expressing the erratic or unbalanced energy which these other people are mirroring back to you.
This is key to dealing with this disruptive energy because any arrogance or unwillingness to adapt and take it higher, could lead to explosive outbursts or ego conflicts. That would only exacerbate the tension or nervousness associated with this transit.
