A few decades ago scientists who were studying macaques on the Japanese islands, discovered that many monkeys ignored the fruits that washed ashore on the beach. After all they were covered in sand. However, there was one female that did know what she had to do with them. She picked the fruits up, walked over to a well, washed them and ate them. It didn't take long before other, especially younger macaques, 'aped' this behaviour, and also enjoyed these sweets. This group slowly expanded further, until apparently a switch took place in the consciousness of the group, and from one day to the next all monkeys started washing their fruits. And not only on their island, but also on the surrounding islands. Even though these monkey colonies were not in contact with each other.
We humans are with our individual consciousness also in contact with this collective consciousness. And not only our knowledge is part of this 'field', also all our thoughts and intentions are incorporated in it. It determines who we are, as a species, and what our world looks like. When an individual has a new idea, then from that moment on it's part of the collective consciousness, and it's easier for others to have the same idea.
The reality you experience is a result of a consensus in the collective consciousness of humanity. You and everyone around you has been conditioned to believe and perceive along certain lines. You have been programmed to be self-limiting. But you still retain the ability to reprogram yourself and the reality you see before you.
Every experience that you have is added to the pool and is shared by every other human on a deep and unconscious level. There is in actuality no completely private thought or experience that you can have that won’t also have an impact, however imperceptibly on humanity as a whole.
It can no longer be argued that there is not a concerted effort by certain interests to control your perception of reality. From the time you enter this life you are bombarded with indoctrination from all sides that the world is certain way and that you are small and powerless. This view is relentlessly reinforced by every facet of society. Starting with your parents and continuing through every perceived authority you will encounter.
Everything is connected. We are one and many. Perception is reality and we have to help our fellows to realize their power to manifest a better world.
