At first it was ancient wisdom which stated that we are one with the universe, that everything is interconnected, that all is one.
Then later modern science caught up with this idea. Now quantum physicists say exactly the same thing – in a subatomic level everything is interconnected.
In the 1970s chemist James Lovelock formulated the famous Gaia hypothesis which proposes that all organisms and their inorganic surroundings on Earth are closely integrated to form a single and self-regulating complex system, maintaining the conditions for life on the planet.
This symbol is presented like a metaphor of us and our earth. It is a big organism and we, people, are parts of this organism; we are not separate. And the earth is also just a part of an even bigger organism. Our earth is like a tree with roots that extend to the vast cosmos. Everything is interconnected.
"A human being is a part of the whole called by us universe, a part limited in time and space. He experiences himself, his thoughts and feeling as something separated from the rest, a kind of optical delusion of his consciousness. This delusion is a kind of prison for us, restricting us to our personal desires and to affection for a few persons nearest to us. Our task must be to free ourselves from this prison by widening our circle of compassion to embrace all living creatures and the whole of nature in its beauty." – Albert Einstein
