Everything is vibrational energy and the frequency of that vibration determines the form it creates - a chair, your heart muscle, the light from the sun.
The air is thick with vibrations. So it is a simple truth that connectivity transcends what we can see, hear and touch. We can be affected by music, by the energy of our thoughts and emotions, or of the environments we are in. For example, there is a distinct difference between being at the ocean versus a football stadium. The vibrational frequency is different and it moves through the cells of our body. Sometimes we meet people we are attracted to and others we wish to avoid. You are responding to the vibration in their system and how it is amplifying in yours.
It is interesting to consider everyone and every situation as a mirror in this way. What does this person show you of yourself? What are you seeing in the other that you are refusing to acknowledge in yourself. For better or for worse.
We can use this attunement in favour of our collective opening. If everything is connected, we can see each other as a vibrational or energetic mirror. One person's fear may resemble another’s. In other words, it's a vibrational match. It can be felt, recognised and integrated together so as to release it's grip on us, so to speak, and we can live more openly. Likewise we may have a vibrational match with the same person, of a particular openness to something else. Lots of laughter and fun are experienced in these areas with them.
