Human beings are a part of a whole, called by us “the Universe”, a part limited in time and space. We experiences ourselves, our thoughts and feelings as something separated from the rest — a kind of optical delusion of 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. Nobody is able to achieve this completely, but the striving for such achievement is in itself a part of the liberation and a foundation for inner security.
Albert Einstein.

Someone as talented and intelligent as Albert Einstein can know on a deep, scientific, and physical level that it’s impossible for any of us to be truly separate. After all, each breath we take is made up of molecules which have passed through so many beings. How could we exist apart?
Also, someone as insightful and heartfelt as Thich Nhat Hahn can also reveal how we are interconnected and inter-are. Even looking into a cup of tea or a cloud, he reminds us that the entire universe is connected to and through us.
