Synchronicity is a concept, first introduced by analytical psychologist Carl Jung, which holds that events are "meaningful coincidences" if they occur with no causal relationship yet seem to be meaningfully related.
I will define synchronicity as the alignment of your multidimensional self and your physical reality.
Synchronicity is an amazing phenomenon that many people experience when they start their conscious journey. We often see repeating numbers, or we see patterns of certain ideas expressed in our external reality throughout the day. Synchronicity is often a sign that we are in alignment with some grand manifestation beyond what we can perceive.
Our ability to experience synchronicity depends on our alignment with our greater purpose. This alignment depends on the attunement of our chakra centers, or the energy vortexes that connect us to our multidimensional self. There are seven main chakras, each vibrating at a certain frequency range. Each frequency range represents a dimension of consciousness. As we learn to embody these frequency ranges fully in the present moment, we are able to combine more dimensions of consciousness together. This is what I call multidimensional consciousness.
Luckily, you don't need to know all of this to experience synchronicity! Synchronicity can be experienced once you are open to experiencing it. When you do experience it, you DO NOT need to assign meaning to these strange experiences and/or signs. If you are unsure of what something may mean, that is fine! Just let what stands out to your conscious awareness, stand out to you. Notice it without any attachment to assigning meaning to it. If there is a special message for you, you will get it eventually. This may happen hours, days, weeks, or years later. However, if you are attached to assigning meaning, you may distort the moment and prevent yourself from getting any kind of message at all!
In the above video, the bird aligning with my dancing seemed to symbolize that I was in alignment with nature. I was dancing with the intent to embody the element of fire. We may think of fire as involving very explosive movements. However, fire can also be very calm, controlled movements. After I was able to embody fire in this way, I was able to calmly surface some pent up emotions from my subconscious and deal with them in the present moment.
