It only takes 88 days for Mercury to orbit the Sun which means that at multiple times of year an optical illusion occurs where it appears Mercury goes backwards while Earth zips around its orbit.
Mercury is the planet of communication which is why all things to do with communication seem to struggle a bit when Mercury is in retrograde. Have you ever noticed that the computers seem slower, messages are being received, phones cut out more, etc. It can also affect travel.
What to do? Breath.
Reach for these crystals and embrace the flow of the Universe.
It's all going to be okay. Don't stress, just laugh at it. Life is always happening the way it's meant to. Embrace the retrograde.
Journal. Ask yourself where in your life can you relax into things seemingly to be going backwards? What are the lessons and the positives to this?
