A month ago I had no idea what that meant, but after hearing so much about it, I decided to do some research.
In a nutshell: About 3 times a year for 3 weeks or so, Mercury slows down so much that it appears to be going backward. Mercury rules things like communication and travel, so it is recommended that people pay extra attention during retrogrades as these aspects can get a bit muddied. However, this period isn't only about delayed flights and miscommunication. It is also a valuable opportunity to sit back, take a breather and prepare for the next step. How fitting that Mercury in Retrograde coincides with the June newsletter.
“…The coming retrograde will be an extremely important one showing us how to get past internal arguments between past realities and current necessities, and give us one look back so we can get clear about how to shape our social expression with skill and beauty to reveal to others our internal values. We can see what we need to learn relative to recent critical decisions, and how to take a look back on different methods and possibilities."
My own personal take on it: It is of paramount importance to set goals as well as have dreams & expectations of what you want your life to look like. However, it is important to stay realistic and release expectations when necessary. Work hard at what you have control over by creating opportunities to the best of your ability, then be open to what comes to you. Sit back sometimes and assess the situation. What is working, what is not and what shifts need to be made in order to get on the right track? Giving up because something is difficult is not the answer. If you are truly following your dream and something isn't clicking, then release your expectation of what success is supposed to look like.
Don't get caught up on one vision/version and become narrow minded. Be a wide vessel for ideas and opportunities to flow through.
Here is an interesting take on it. This particular article was written for a retrograde in 2013, but is still valid now! And while there is just over a week left of the June 2014 retrograde, there will be many more to come.
